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 ...
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, ...
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 ...
A numerical study of local heat transfer and velocity distributions between blockages with holes in a rectangular channel
(Texas A&M University, 2002)
A numerical study has been conducted to understand the distributions of the local heat transfer coefficient and the local velocity for turbulent air flow past two or three blockages in a rectangular channel. The blockages ...
Experimental determination of foundation properties without shaker tests
(Texas A&M University, 2002)
The foundation of a rotating machine can contribute to the dynamics of the system, and therefore it becomes essential to include the foundation in the model to predict the correct response of the system. The primary objective ...
Continuous shearing of dense and wet granular materials in a torsional rheometer
(Texas A&M University, 2002)
Research on granular materials is motivated by the need to understand certain geological processes and to design better bulk handling devices in industrial processes. Since granular materials exhibit properties of solids ...
Influence of material, lay-up, and geometry on the radius of curvature of spoolable composite tubulars
(Texas A&M University, 2002)
The focus of this study is the design and analysis of the structural behavior of filament-wound composite tubes capable of being coiled onto large spools for ease of storage, handling, and installation. The objective is ...
The effect of preceding elbows on aerosol deposition in subsequent flow elements
(Texas A&M University, 2002)
The wall losses in tubing elements due to the secondary flows established in an elbow were experimentally determined. Monodisperse, liquid aerosol particles of sizes 5-20 []m were used to perform the tests. The tests were ...
