Design And Analysis Of An Instrument System For Rheological Testing Of Whole Blood Samples, Robert Rimvydas Sinusas

Dissertations

The dissertation covers the conceptual design of a rheometer for testing whole blood samples through to the clotting state. While the design aims at increased measurement accuracy, the design employs well known technologies and available components.

The main reason for preoccupation with blood testing is that recent investigations have indicated that physiological disorders can be correlated with rheological properties of blood. The pursuit of an improved means of correlation is initiated with a survey of the rheological properties of blood. The relevance of these blood properties is then discussed. From this discussion a broader blood model is developed as a …

The Interpretation Of Infrared And Raman Spectra Using Pattern Recognition, John Martin Comerford

Dissertations

An automatic classification of chemical compounds by computer processing of digitized spectral data is presented. The classification system is based on a branch of artificial intelligence known as supervised learning, and used binary linear classifiers to identify compounds as alcohols, esters, ethers, ketones or compounds containing double bonds.

Each of the 1117 spectra in volume one of Sadtler's Standard Raman Spectra was coded using a scale from 0 to 9 in the range from 4000 to 200 cm^-1. One hundred and twelve readings were taken on each spectrum. These data were then examined using pattern recognition techniques, and …

Effect Of Mixing On Polymerizations In Batch Reactors, John Guy Steenrod

Theses

The effects of mixing on polymerizations in batch reactors are examined theoretically for initiations by thermal decomposition of catalyst and by absorption of ionizing radiation. Mathematical expressions for predicting the first three moments of the dead polymer size distribution are presented. Two extreme mixing states. perfect and no mixing. are considered. It is shown that in batch reactors mixing in any direction in which nonuniform initiations exist increases the polymerization reaction rate and the number average molecular weight, and decreases the weight average and the polydispersity.

Experimentally, the effects of mixing were studied in a solution polymerization system, in a …

The Theory Of Multiple Measurements Techniques In Distributed Parameter Systems, Babajimi Claudius Okunseinde

Dissertations

A comprehensive theory of multiple measurements for the optimum on-line state estimation and parameter identification in a class of noisy, dynamic distributed systems, is developed in this study. Often in practical monitoring and control problems, accurate measurements of a critical variable are not available in a desired form or at a desired sampling rate. Rather, noisy independent measurements of related forms of the variable may be available at different sampling rates. Multiple measurements theory thus involves the optimum weighting and combination of different types of available measurements. One of the contributions of this work is the development of a unique …

Particular emphasis is put on determining the amount of diluent required to attain 98% conversion of methane at an outlet temperature of 723°K. The program also determines the reactor volume necessary to achieve the specified conversion, and the …

The Steady State Heat And Temperature Distribution Of A Hot Sphere Within An Infinite Wedge, David W. Horwat

Theses

This thesis presents a mathematical model of the steady state heat and temperature distributions of a hot sphere located along the midplane of an infinitely long wedge of any arbitrary central angle. The heat and temperature distributions of this geometric configuration are of immense value, since through the use of this model as a wedge shaped unit cell the description of any number of hot spheres, arranged in a regular planar array can be immediately determined.

The method of reflections is used to solve Laplace's equation , V²T=O , analytically using the sphere and the wedge walls as …

Optimal Performance Of Equilibrium Parametric Pumps, Joseph A. Manganaro

Theses

An examination of the conditions required to obtain the optimal performance of semicontinuous and continuous parametric pumps, defined by the achieving of the maximum possible solute free product for a given column height, was undertaken. The model system sodium nitrate ? water on an ion retardation resin adsorbate was employed. Equations defining maximum values of certain important parameters such as the bottom product flow rate and reservoir displacement rate were developed by extending previous theories of parametric pumping. Experimental runs were carried out using parameters whose values were both less than and greater than the maximum values predicted for optimal …

Rheo-Optical Properties Of Polyisobutylene, Russell B. Biss

Theses

This study presents quantitative experimental data on the various stress-optical characteristics of polymer liquids, specifically, polyisobutylene. Through the use of a concentric cylinder rheogoniometer and a rotational viscometer, the temperature effects of a newtonian polyisobutylene liquid. was studied and was found to have a stress-optical coefficient independent of shear stress and minor temperature changes. The experiments confirm that the birefringence is a known function of the extinction angle and the shear stress. Various polyisobutylene liquids were used in a simple flow device to observe the birefringence in the 1-3 plane and the 2-3 plane. The results indicate that the 1-3 …

A Nonlinear Viscoelastic Model, Yon-Li Shangkuan

Dissertations

A nonlinear viscoelastic model has been developed to describe the non-Newtonian viscosities and the primary normal stress differences of high polymers at steady-state shearing flow.

It has been demonstrated that the Huang-Shangkuan model gives the best representation of the experimental data for a wide range of shear rates. In the high shear rate region the Huang-Shangkuan model is distinguished among other models by its capability to predict the nonNewtonian viscosities and the primary normal stress differences Which the other models fail to predict.

Continuum mechanics, Lodge's network theory and Rouse's theory provide specific information in developing our model. The theoretical …

An Experimental Study Of The Separation Of Multicomponent Mixtures Via Thermal Parametric Pumping, Wayne Weywen Lin

Theses

A thermal continuous parametric pump for separating multi-component mixtures was experimentally investigated using the model system toluene-aniline-n-heptane on silica gel adsorbent. A simple method for predicting separations is presented and is found to be in good agreement with the experimental results. The method, based on an equilibrium theory, is under the assumption that a multicomponent mixture contains a series of pseudo-binary systems, each system consisting of one of the solutes as one component and the common inert solvent as the other component.

Densities Of Polar And Non-Polar Compounds And Their Mixtures, Peter Norman Notwick

Theses

Two principal studies were conducted as part of this thesis: evaluation of existing correlations for predicting densities of polar and non-polar liquids and their mixtures and experimentally measuring the densities of certain liquid systems.

Utilizing a modification of the simple picnometer experimental method, data were obtained for both pure compounds and liquid mixtures. Comparison of the pure compound data with available literature sources established the reliability of the technique.

The results of the correlation comparison indicate that the Riedel equation, is the most generally reliable for predicting the densities of pure "normal" compounds. Lydersen, et al., prepared tables for the …

An Experimental Study Of Parametric Pump, Khalid Omar Ranginwala

Theses

In this research for Master's Project, the possibility for separation of glucose and fructose by parametric pumping was investigated. In this research activated carbon was used as adsorbent. First Langmuir's isotherms for glucose and fructose were experimentally found. These results were utilized in the thermal parametric pumping. The pump was run semicontinuously. Parametric pumping was also carried out with KCl +H₂O solution using a resin as adsorbent, and the 'b' value of KCl was found.

An Experimental Study Of Equilibrium Parametric Pumps, John A. Park

Theses

Parametric pumping is a separation process characterized by periodic changes in axial displacement, coupled with synchronized changes in some variable affecting the position of the interphase equilibrium. Both continuous and semicontinuous pumps were investigated at various operating conditions using a model system of toluene-n-hep-tane on a silica gel adsorbent. It has been shown that when the penetration distance for the cold cycle is less than or equal to that for the hot cycle and the height of the column, the pump has the capacity of complete removal of solute from one product stream. A quantity which is important in determining …

A Study Of Fluid Flow Entering A Sharp-Edged Channel, Rocco Racano

Theses

Experimental investigations were carried out on an newtonian fluid In the two dimensional case through the regions of a sharp-edged entrance and exit. Qualitative and quantitative results were compared to a variation of a two dimensional case of converging flow in a capillary as originally derived by Oka and proposed by Philippoff. In addition velocity profiles were taken in the entrance region. Furthermore, the effect of temperature gradients in the slit region with their resulting optical effects were considered. The methods used to obtain these goals were photoelasticity and streak photography.

Results were four, to be consistent with the theory …

Separation Of Gas Mixtures Via Batch Parametric Pumping : A Theoretical Study, Jose G. Lopez

Theses

An equilibrium plug?flow model, for the batch isothermal separation of a binary gas mixture in a pressure changing parametric pump, was investigated for the system propane?argon on carbon, with the aid of a G. E. Pack 4020 computer. Separation factors comparable to a temperature changing parametric pump are predicted by the model. A change in pressure of the gas mixture may be carried out very rapidly, compared with a temperature change of similar magnitude. The effects of temperature, pressure, concentration, and penetration are discussed.

The objections to this model which have appeared in the literature are discussed, and the model is viewed in the light of other work in the field. A set of guidelines to aid the "second generation" model building effort is developed. The actual construction of a model which attempts to follow these guidelines is described. First, the …

Representation And Characterization Of Thixotropic Fluids, Huei-Hsiung Wang

Dissertations

Thixotropy is a time-dependent rheological behavior of a group of fluids which are characterized by an isothermal reversible breakdown induced by a mechanical disturbance. Based on this definition, a mathematical model of reversible degradation kinetics is set up. Its development leads to two equations which represent quantitatively the hysteresis loop and torque-decay curve. These equations consist of five independent parameters with their physical meanings. These parameters can be used to characterize the properties of thixotropic materials.

The original Weissenberg Rheogoniometer was modified to measure the thixotropic behavior of blood with the step change and the ramboid change of shear rate. …

Antoine Type Equation For Liquid Viscosity Correlations, Edward Goletz Jr.

Theses

A modified Andrade⁴ equation, similar to the Antoine equation for vapor pressure-temperature correlations, was developed for liquid viscosity-temperature correlations. Included in the investigation were the following compounds: n-alkanes (C₂-C₂₀), n-alkenes (C₂-C₂₀), n-alkyl benzenes (C₆-C₁₀), n-alkyl cyclohexanes (C₆-C₂₂), and fifteen polar compounds. Except for propene, errors of less than 5% were obtained. Normal heptadecane was used to compare correlations developed by Andrade⁴, Walther²⁰, and Doolittle⁹, with the modified Andrade equation. The latter was found to give the best …

Stress-Relaxation Of Cross-Linked Polyethylene At Elevated Temperature, Ravio Luik

Theses

Polyethylene because of its excellent chemical, physical, mechanical and electrical properties, as well as its easy adaptability to extrusion, molding and other processes and its low cost has become a very widely used material for hundreds of applications. But, because it is a thermoplastic, it also deforms and flows when temperatures approach or exceed the crystalline melting point. This handicap, however, can be reduced by crosslinking the polymer chains and thereby converting the thermoplastic to a thermoset material. To further expand the possible uses of this popular material and to further improve the properties, fillers and antioxidants may be compounded …

A Theoretical Study Of Continuous Parametric Pumping At Constant Temperature, Philip Weingartner

Theses

A continuous parametric pump, operating at constant temperature with pressure as the driving force, is analyized by means of an equilibrium theory. A thorough explanation of the process and the resulting mathematical model reveal how the parameters effect pump performance. The experimental data cited agree well with the analytical results in the CO₂-He on silica gel system. Complete removal of the solute from one of the product streams can be achieved through the proper selection of penetration distances and pressure levels.
