Effect of doping in Bi-Pb-Sr-Ca-Cu-O superconductor composites
(Texas A&M University, 2001)
The goal of this thesis is to analyze the solid solubility limit of dopants in Bi-Pb-Sr-Ca-Cu-O superconductors. We have studied the effect of Mn doping Bi-Pb-Sr-Ca-Cu-O. The electrical resistivity and critical temperature ...
Automatic Calibration of a Building Energy Performance Model and Remote Fault Detection For Continuous Commissioning Using a Global Optimization Program
(Texas A&M University, 2002)
Building simulation models have been used for many years to forecast and analyze a building's energy consumption. Over the past several decades, building energy simulation programs and input techniques have been developed ...
Vibration suppression of laminated composite plates using embedded smart material layers
(Texas A&M University, 2000)
In this study, a complete theoretical formulation of laminated composite plates with integrated smart material layers that serve as sensors and/or actuators is presented for the vibration suppression of laminated composite ...
Analysis of a flexible polymeric film with imbedded micro heat pipes for spacecraft radiators
(Texas A&M University, 2001)
In response to the pursuit of interplanetary travel and a continuous human presence in space, there is increasing focus within the space industry on spacecraft designs that change configuration within the space environment. ...
Grain refinement in bulk pure tantalum using equal channel angular extrusion
(Texas A&M University, 2001)
For this study, the effectiveness of equal channel angular extrusion (ECAE) to improve the material properties and processing characteristics of vacuum arc remelted (VAR) pure tantalum was determined. The primary objectives ...
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 ...
Experimental response of gas hybrid bearings for high speed oil-free turbomachinery
(Texas A&M University, 2002)
The present investigation advances the analysis and experimental validation of simple gas bearing configurations with static and dynamic force characteristics desirable in high-speed turbomachinery. Comprehensive experiments ...
Understanding the friction factor behavior in liquid annular seals with deliberately roughened surfaces, a CFD approach
(Texas A&M University, 2002)
Bulk flow theory has been widely used to estimate annular seals dynamic coefficients. To predict the flow behavior through the seal, this theory relies on empirical friction factor correlations based on pipe data. Several ...
Rotordynamic evaluation of hybrid damper seals with metal mesh elements
(Texas A&M University, 2003)
Metal mesh hybrid damper seals (MHS) were proposed to be an alternative for brush hybrid pocket damper seals (PDS) in turbomachinery. The metal mesh hybrid damper seal is a hybrid of the pocket damper seal and the metal ...
