Abutment-Thermal Interaction Of A Composite Bridge, David B. Lewis

CCFSS Library (1939 - present)

A two-span test structure, with tie-rods to similate approach-slab forces, was subjected to thermal loading. The resultant strains and deflections are correlated with those obtained from a prior theoretical study. It was concluded ~hat the theoretical procedure provides a rational method for predicting the thermal behavior of composite-girder bridge structures.

A New Experiential Course In Engineering Management, Donald S. Remer

All HMC Faculty Publications and Research

Institutions with undergraduate programs of the engineering management type often find their introductory courses to be popular electives for students in more traditional engineering disciplines, while in other cases specific courses from business management or industrial engineering departments are elected. Where none of these options are available or suitable, engineering schools are well advised to provide one or two key courses to provide at least an introduction to the management problems their graduates will face. At Brown University, according to Prof. Barrett Hazeltine, a series of two courses in engineering management serve this function; more than half of Brown's undergraduate …

Thermosiphon System, Florida Solar Energy Center

FSEC Energy Research Center®

In a THERMOSIPHON SYSTEM, cold water from the bottom of the elevated storage tank flows to the lowest point in the system (which is the bottom of the solar collector).

As it is warmed it becomes less dense and flows up to a side port near, but not at, the top of the storage tank. If the tank is about two feet above the top of the collector, the system will not back-siphon at night. If back-siphoning were to occur, the warm water would be cooled during its passage through the dormant collector. Thermosiphoning systems have no moving parts and …

Non-Linear Behavior Of Unbraced Two-Bay Reinforced Concrete Frames, Mehdi Shadyab

Dissertations and Theses

In this investigation, the primary objective was to study the nonlinear behavior of unbraced two-bay concrete frames and to determine the extent to which ultimate load theory or limit design can be applied to these structures. The frame behavior was investigated analytically by two methods. In the first method the frame stability equation was derived assuming that members of the frame possess an elasto-plastic moment-curvature relationship. This stability analysis was also carried out by another model consisting of a column attached to a linear spring and carrying the total frame load. The second method was through a computer program which …

Electronic Fuel Injection Techniques For Hydrogen Powered I.C. Engines, Art Maccarley, W. D. Van Vorst

Electrical Engineering

Numerous studies have demonstrated the advantages of hydrogen as a fuel for Otto Cycle engines due to high thermal efficiency and low exhaust pollutant levels. Characteristic of hydrogen engine operation using premixed intake charge formation is a problem of pre-ignition resulting in an intake manifold “backfire”. Additional problems include high NO_x production when using certain equivalence ratios and power output degradation due to low fuel energy/volume density.

Techniques for direct and port fuel injection are discussed as means for overcoming these problems. Emphasis is placed on the need for total engine control, integrating control of fuel injection, ignition timing, …

The Limnological Status Of Lake Mead And Lake Mohave Under Present And Future Powerplant Operations Of Hoover Dam, Larry J. Paulson, John R. Baker, James E. Deacon, U.S. Water And Power Resources Service

Publications (WR)

The ever-increasing demand for energy in the southwest has led to a search for additional sources of power generation. Coal-fired powerplants currently provide most of the baseline energy in the southwest, but this must be supplemented with hydroelectric power during periods of peak demand. In order to provide additional peaking power, the U.S. Bureau of Reclamation is considering a number of projects to modify existing hydroelectric facilities, or add new facilities in the Lake Mead Recreation Area. The Hoover Powerplant Modification Feasibility Investigation was authorized by Congress on December 16, 1975 to determine the feasibility of: (i) adding one or …

An Investigation Into The Solution Of Three Dimensional Elastostatic Problems Using The Boundary Integral Technique, David Campbell Aldrich

Retrospective Theses and Dissertations

The boundary integral technique was implemented in a computer code for the general static analysis of three dimensional elastic solids. The was based on a formulation of the problem in which the governing boundary equation is developed from the known solution to Kelvin's problem, by the application of Betti's reciprocal relationship. Modeling the boundary of the region being analyzed with plane elements and assuming the tractions and displacements constant across these elements leads to a set of simultaneous algebraic equations approximating the boundary integral equation. Numerical techniques are used in the computer code to assemble and solve this set of …

Statistical Fading Of A Plane Optical Wave In Atmospheric Turbulence, John F. O'Hara

Retrospective Theses and Dissertations

A formula for the average fade time of the intensity of a plane optical wave traveling through atmospheric turbulence is developed. The model employed involves isotropic, homogeneous statistics using a lognormal distribution for the channel. The analysis is based on the fact that the logarithm of the irradiance is normally distributed and uses the work of S. O. Rice who developed such an expression for a zero mean, Gaussian process. The analysis employs the covariance function and the Taylor frozen turbulence hypothesis which results in an expression for the autocorrelation function.

Ground Driven Powered Tillage, Larry G. Wells, E. M. Smith, D. E. Hammett, H. J. Thompson Jr.

Biosystems and Agricultural Engineering Faculty Publications

A ground driven powered tillage device is described which utilizes a passive rolling coulter propelled through the soil by a prime mover. The reaction torque imparted by the soil to the coulter is delivered via a torque transfer unit to a powered tillage blade. The tillage blade rotates counter to the direction of the passive rolling coulter and prepares a tilled furrow of some predetermined depth for seed placement and coverage.

Analysis is presented in which the torque developed by a passive rolling coulter engaging the soil is predicted. A relationship is presented for determining the velocity ratio between the …

Analysis And Testing Of Powered Tillage Blades, Larry G. Wells, E. M. Smith, D. E. Hammett

Biosystems and Agricultural Engineering Faculty Publications

Fundamental design considerations for powered rotary tillage blades are presented and discussed. The relationship between blade angular velocity and the geometric dimensions of cutting edges is specified for tillage blades rotating counter to the direction of travel and assuming a typical forward speed for tillage.

Analyses showed that a powered blade rotated opposite to the direction of travel can be operated at relatively lower angular velocities than can one rotated in the direction of travel to achieve equivalent blade velocity and acceleration relative to the soil. Furthermore, a blade rotated opposite to the direction of travel requires relatively lower power …
