Simple shear processing of bulk BI₂TE₃ alloys
(Texas A&M University, 2001)
The objective of this work is to determine the appropriate extrusion conditions of cast Bi₂Te₃ alloys via equal channel angular extrusion (ECAE) to produce material that has a fine grain size (5~30[]m), uniform grain ...
Micro-fluidic flow control using the electroosmosis
(Texas A&M University, 2001)
The objective of the proposed thesis is the introduction and development of micro-scale particle image velocimetry ([u]-PIV) to study the micro-scale flow field in the electroosmotic flow, which is the flow produced by the ...
An experimental and computational leakage investigation of labyrinth seals with rub grooves of actual size and shape
(Texas A&M University, 2001)
A large scale water test facility and a commercial CFD computer program were used to investigate labyrinth seals with rub grooves of actual size and shape found in aircraft engines. The 2-D test rig cases focused on the ...
Effect of test conditions and sample configuration on the AMTEC electrode/electrolyte characteristics measurements in the Sodium Exposure Test Cell experiment
(Texas A&M University, 2001)
An experimental investigation was conducted to determine the effect of test conditions and sample configuration on the AMTEC electrode/electrolyte characteristic measurements in a Sodium Exposure Test Cell (SETC). The ...
A slit impactor utilizing a transpirated impaction surface for collection of bioaerosols
(Texas A&M University, 2001)
In recent years, there has been a growing concern of possible attacks against the United States by other countries using biological weapons. In response to this concern, the U.S. government has increased its defensive ...
Measurement and analysis of gas turbine blade endwall heat transfer
(Texas A&M University, 2001)
For many years it has been recognized that the design of an efficient high pressure turbine with adequate component life is crucial to the success of any gas turbine engine project. Inherent in the design process is the ...
Evaluation of Fin Staging Methods for Minimizing Coil Frost Accumulation
(Texas A&M University, 2001)
Frost formation on heat pump evaporators is a source of degradation in the performance of heat pumps during heating mode operation. This research sought to determine whether staged fins on outdoor evaporators could slow ...
Recovery of signals measured by inaccurate sensors
(Texas A&M University, 2001)
The main problem investigated in this research is the recovery of signals measured by inaccurate sensors, which normally has a tendency of distorting signal information, both in the time domain and frequency domain. A ...
Characterization of residual stress relaxation in welded steel plate using TAP-NDE and wavelets
(Texas A&M University, 2001)
This thesis presents the characterization of residual stress relaxation in a welded ASTM 1018 steel plate by using the Thermo-Acousto-Photonic Nondestructive Evaluation (TAP-NDE) technique and the Gabor Wavelet Transform ...
The effects of moisture and particle size of feedlot biomass on co-firing burner performance
(Texas A&M University, 2001)
Biomass (conventional and non-conventional) fuels co-fired with coal for power and steam generation are being tested and evaluated at several generation stations in the United States. The co-firing technology is expected ...
