Development and use of an interactive computer simulation for generalized technical and economic assessments of cogeneration systems
(Texas A&M University, 1997)
The development and use of a computer simulation program incorporating an interactive spreadsheet software package to evaluate the technical and economic feasibility of cogeneration systems is described. Three hypothetical ...
Synthesis of reduced order prefilters for multivariable tracking
(Texas A&M University, 1997)
A primary disadvantage of using an internal model to achieve multivariable tracking is the high order of the internal model. In situations where it is known that each output is to track only its associated reference input, ...
Strain uniformity through equal channel angular extrusion
(Texas A&M University, 1997)
The objective of this work is to characterize the processing effects of equal channel angular extrusion (ECAE) on aluminum 6063, copper I 10, and filamentary Cu/NbTi composite superconductor. The major objective of this ...
CFD based rotordynamic coefficients for labyrinth seals and impeller leakage paths
(Texas A&M University, 1997)
The objective of this thesis is to explore the possibilities of Computational Fluid Dynamics to predict rotordynaniic coefficients for complicated geometries and high speed flows. Circulating flows, common in labyrinth ...
An experimental investigation of critical heat flux in subcooled internal flow
(Texas A&M University, 1997)
An experimental investigation has been conducted to determine the critical heat flux for subcooled refrigerant-11 and refrigerant-113 flowing upward in a vertical cylindrical tube. Critical heat flux (CHF) values are ...
Coherent testing and simulation of composite blade repair
(Texas A&M University, 1997)
The objective of this research program is to experimentally and computationally determine the static and fatigue response for two methods of repair to an E/Glass-Epoxy sandwich laminate. The proposed methods of repair are ...
Using ultrasonic techniques to predict fracture toughness of AISI 4137 alloy steel
(Texas A&M University, 1997)
Previous studies have indicated the possibility of using ultrasonic attenuation as a nondestructive tool for predicting fracture toughness of metals. In all these studies, the fracture toughness was varied by changing the ...
Genetic algorithm based tomographic flow visualization
(Texas A&M University, 1997)
A new nonlinear tomographic flow visualization technique for use in limited data situations is developed using techniques from the emerging field of evolutionary computing. The new technique uses both pure and hybrid genetic ...
Consolidation of aluminum 6061 powder by equal channel angular extrusion
(Texas A&M University, 1997)
Equal channel angular extrusion is a promising approach to obtaining full density in powder metallurgy applications. This method can impose large effective deformations through uniform shear strain. Aluminum alloy 6061 ...
Effect of unsteady wake passing frequency on boundary layer transition on the concave surface of a curved plate
(Texas A&M University, 1997)
The unsteady boundary layer behavior on the concave surface of a curved plate is investigated. Detailed experimental investigations are carried out to study the effect of unsteady wakes on the boundary layer transition ...
