Experiments to model the rotordynamic behavior of rub rings and bumpers
(Texas A&M University, 2000)
Rub-impact between rotors and stators is a widely studied phenomenon due to its deleterious effects on rotating machinery. When large amplitudes of vibration are developed in rotors due to either imbalance or triggered ...
Ultrasonic measurement of residual stress relaxation in welded steel plates using critically refracted longitudinal waves
(Texas A&M University, 2000)
This study investigates whether or not there is a measurable amount of residual transverse stress relaxation in welded steel. This was determined by using two different methods of stress measurement. These methods involved ...
Blade tip clearance effect on the performance and flow field of a three stage axial turbine
(Texas A&M University, 2003)
The effect of a 1.5 % blade tip clearance on a rotating three stage turbine under different operating points was investigated using radially and circumferentially traversed five hole pressure probes. The probes were used ...
Evaluation of Mixing in Three Duct Configurations and Development of a Generic Tee Plenum System (GTPS) for Application to Single Point Aerosol Sampling
(Texas A&M University, 2003)
A Generic Tee Plenum System (GTPS) based on three different duct systems (Configuration-I, II and III) used in nuclear facilities has been developed which creates suitable conditions for single point representative sampling. ...
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 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 ...
