Hydrodynamics Of Dispersed Liquid Droplets In Agitated Synthetic Fibrous Slurries, Theodore J. Heindel, Feler Bose, S. Mostafa Ghiaasiaan
Hydrodynamics Of Dispersed Liquid Droplets In Agitated Synthetic Fibrous Slurries, Theodore J. Heindel, Feler Bose, S. Mostafa Ghiaasiaan
Theodore J. Heindel
The hydrodynamic and liquid particle dispersion processes in agitated vessels containing dilute liquid−liquid dispersions, and dilute liquid dispersions in synthetic fibrous slurries, were experimentally studied. A transparent cylindrical vessel 25 cm in height and 15.5 cm in diameter equipped with a six-blade impeller, with geometric proportions representing the standard vessel configuration, was used. The steady-state size distributions of molten wax particles, which constituted 1% by weight of the mixture everywhere, in pure water, and in aqueous slurries with 0.1%, 0.5%, 0.8%, and 1.0% consistencies of nylon fibers, were measured using sampling and microscopic image analyses. The average nylon fiber length …

Pollutant Atmospheric Emissions From Portuguese Kraft Pulp Mills, João F. Gomes
João F Gomes
This paper describes systematic work done in the field of atmospheric emissions from Portuguese Kraft pulp mills. This study led to the determination of emission factors from stationary sources that proved to be an important tool to assess the need for investment on air pollution abatement equipment.
Transformation Of Tnt By Aquatic Plants And Plant Tissue Cultures, Joseph B. Hughes, Jacqueline V. Shanks, Mindy Vanderford, John Lauritzen, Rajiv Bhadra
Transformation Of Tnt By Aquatic Plants And Plant Tissue Cultures, Joseph B. Hughes, Jacqueline V. Shanks, Mindy Vanderford, John Lauritzen, Rajiv Bhadra
Jacqueline V. Shanks
The ability of plants to uptake and transform 2,4,6-trinitrotoluene (TNT) was investigated using the aquatic plant Myriophyllum spicatum, axenic Myriophyllum aquaticum, and Catharanthus roseus hairy root cultures. Studies demonstrate that Myriophyllum, with or without its periphyton, and C. roseus transform TNT. Low concentrations of aminated nitrotoluenes (2-amino-4,6- dinitrotoluene and 4-amino-2,6-dinitrotoluene) were observed in the extracellular medium and tissue extracts. Primary products of transformation were not identified, and mineralization was not observed. Mass balances demonstrate that a large percentage of the unknown TNT transformation products were associated with the plant. This fraction could be at least partially recovered from the plant …

Rheology Of Dense Bubble Suspensions, Ashok S. Sangani, Sang-Yoon Kang, Heng-Kwong Tsao, Donald L. Koch
Ashok S. Sangani
The rheological behavior of rapidly sheared bubble suspensions is examined through numerical simulations and kinetic theory. The limiting case of spherical bubbles at large Reynolds number Re and small Weber number We is examined in detail. Here, Re = p y a^2 / u and We = p y^2 a^3 / s, a being the bubble radius, g the imposed shear, s the interfacial tension, and m and r , respectively, the viscosity and density of the liquid. The bubbles are assumed to undergo elastic bounces when they come into contact; coalescence can be prevented in practice by addition of …
Nusselt Number For Flow Perpendicular To Arrays Of Cylinders In The Limit Of Small Reynolds And Large Peclet Numbers, Ashok S. Sangani, Wei Wang
Nusselt Number For Flow Perpendicular To Arrays Of Cylinders In The Limit Of Small Reynolds And Large Peclet Numbers, Ashok S. Sangani, Wei Wang
Ashok S. Sangani
The problem of determining the Nusselt number N, the nondimensional rate of heat or mass transfer, from an array of cylindrical particles to the surrounding fluid is examined in the limit of small Reynolds number Re and large Peclet number Pe. N in this limit can be determined from the details of flow in the immediate vicinity of the particles. These are determined accurately using a method of multipole expansions for both ordered and random arrays of cylinders. The results for N/Pe^1/3 are presented for the complete range of the area fraction of cylinders. The results of numerical simulations for …

The forces between a silica probe and an n-type TiO2 single-crystal electrode were measured using an atomic force microscope in an aqueous electrolyte solution. These interactions were a strong function of the solution pH, the presence of specifically adsorbed anions, and the TiO2 electrode potential. For a series of pH values, a strong electrostatic repulsion was seen at high pH and decreased as the pH was reduced. At pH values below 5.5, the interaction became attractive. A series of force measurements between SiO2 and n-type TiO2 showed a repulsive interaction when TiO2 was held at negative electrode potentials, which transformed …

Calculations Of Thermodynamic Derivative Properties From The Nrtl And Uniquac Models, Yasar Demirel
YASAR DEMIREL
The local composition models NRTL and UNIQUAC with temperature-dependent parameters have been employed to calculate the surfaces of excess heat capacity, excess enthalpy, and thermodynamic factor, F for binary liquid mixtures. These thermodynamic properties represent the derivatives of the models with respect to temperature and composition.

Thermodynamic Analysis Of Convective Heat Transfer In A Packed Duct With Asymmetrical Wall Temperatures, Yasar Demirel
Thermodynamic Analysis Of Convective Heat Transfer In A Packed Duct With Asymmetrical Wall Temperatures, Yasar Demirel
YASAR DEMIREL
Combination of the first and second law of thermodynamics has been utilized in analysing the convective heat transfer in a rectangular packed duct. Raschig ring type of packing in the air flow passage is used to enhance the heat transfer from uniformly heated front wall to air when the other walls are adiabatic. The packing increases wall to fluid heat transfer considerably, hence reduce the entropy generation due to the heat transfer across a finite temperature difference. However, the entropy generation due to fluid tiow friction increases. The net entropy generations resulting from the above effects provide a new criterior …

Entropy Generation Of Convection Heat Transfer In An Asymmetrically Heated Packed Duct, Yasar Demirel, H.H. Ali, B.A. Abu-Al-Saud
YASAR DEMIREL
An expression for the volumetric rate of entropy generation has been derived and displayed graphically to analyze the convection heat transfer for a fully established flow in a rectangular packed duct with LAt=I6 and H/W=0.125. The top and bottom walls of the duct are heated by constant, asymmetric heat fluxes, while the other walls are insulated that is the L2 thermal boundary conditions. Entropy generation maps reveal the regions where excessive entropy generation occurs due to physical and geometric parameters for a specified task within the system.
