Experimental study of the effects of wakes on separation in low pressure turbine flow
(Texas A&M University, 2003)
The present study, which is the first of a series of investigations dealing with specific issues of low pressure turbine (LPT) boundary layer aerodynamics, is aimed at providing a detailed unsteady boundary flow ...
Optimal internal combustion engine tuning utilizing perturbation/correlation
(Texas A&M University, 2003)
This thesis addresses the application of the perturbation/correlation method to optimizing the torque output of internal combustion engines. This application was inspired by observations of the limitations in current ...
Heat transfer measurements in a two-pass square duct via a transient liquid crystal image method
(Texas A&M University, 2000)
In this research air flow transient heat transfer in a two-pass channel via thermochromic liquid crystals is studied. An 180° turn and rib roughened surface are part of the channel. This geometric combination simulates ...
A comparison of rotordynamic-coefficient predictions for annular honeycomb gas seals using different friction-factor models
(Texas A&M University, 2000)
Predictions of rotordynamic-coefficients for annular honeycomb gas seals are compared using different friction-factor models. Analysis shows that the fundamental improvement in predicting the rotordynamic-coefficients ...
Design of high temperature high speed electromagnetic axial thrust bearing
(Texas A&M University, 2002)
The National Aeronautics and Space Administration (NASA) is researching the magnetic bearings to use it as a better alternative to conventional bearings. This research was to develop an axial thrust electromagnetic bearing ...
Methods and modeling for the reduced platen compression of cancellous bone in the rodent proximal tibia
(Texas A&M University, 2002)
This study focused on the reduced platen compression (RPC) test of cancellous bone in the rodent proximal tibia. The objective was to improve methods for this mechanical test, specifically in the areas of specimen location, ...
Position control of a servopneumatic system using fuzzy compensation
(Texas A&M University, 2000)
The position control of a servopneumatic system in the presence of stick-slip type of friction is investigated. A cost effective, model-free fuzzy compensation scheme is proposed. The fuzzy compensation scheme compensates ...
Development, evaluation, and design applications of an AMTEC converter model
(Texas A&M University, 2002)
An AMTEC converter model was developed and its effectiveness as a design tool was evaluated. To develop the model, requirements of the model were defined, modeling equations were selected, and a methodology for model ...
Caged Molecular Fluorescence Velocimetry to measure meso-to micro-scale thermal flow fields
(Texas A&M University, 2000)
A caged molecular fluorescence velocimetry (caged MFV) system has been developed to measure velocity profiles of thin meniscus flow fields commonly established in micro-scale thermocapillary devices such as micro heat pipe ...
Force measurements in magnetic bearings using fiber optic strain gauges
(Texas A&M University, 2000)
The research presented here develops a new method for measuring forces in magnetic bearings. Fiber-optic strain gauges (FOSGs) mounted to the side of the magnet poles are used to detect the small levels of strain that the ...
