Effect of scale up, stacking, self humidification and use of lightweight components on the performance of a proton exchange membrane fuel cell
(Texas A&M University, 1995)
The effects of various design and operating variables on the performances of a PEM fuel cell were investigated. Performance was evaluated in terms of the polarization curves (cell potential versus current density plots). ...
A manual procedure for assembly sequence planning based on the exploded view method
(Texas A&M University, 1995)
This thesis covers the development of a manual planning procedure based on the computerized method of exploded views to generate an optimal or near-optimal assembly sequence. Care has been taken to minimize iterative and ...
A 3D laser doppler velocimetry study of the upstream velocity profile effects upon the flow field inside an orifice flowmeter
(Texas A&M University, 1995)
Orifice meters are used for the measurement of flow rate, particularly in the natural gas industry. They are relatively simple and inexpensive devices; the flow rate is calculated by observing the pressure drop across an ...
A test rig for the identification of rotordynamic coefficients of fluid film bearings
(Texas A&M University, 1995)
A test rig and measurement procedure to identify the rotordynamic coefficients of generic fluid film bearing elements are described. The test apparatus allows the exchange of test articles without modifications to the basic ...
An experimental investigation of a periodic impingement technique for heat transfer enhancement
(Texas A&M University, 1995)
Experiments are conducted to study turbulent steady state heat transfer and friction for airflow in a wide rectangular channel with periodic longitudinal deflector plates that are affixed to the two primary walls. The ...
The effect of inhibitors on material and mechanical properties of oxidized carbon-carbon composites
(Texas A&M University, 1995)
The carbon-carbon laminates examined in this research program are two-dimensional, eight harness satin weaves with boron carbide (B4C) inhibitor particles and a multi-layer silicon carbide (SiC) coating. These inhibitor ...
Experimental study of nuclear workplace aerosol samplers
(Texas A&M University, 1995)
Monitoring radionuclide effluents has historically been recognized as an important operational activity and a mandatory requirement. US DOE facilities generally require that a continuous air monitor (CAM) instrument be ...
Simulation and study of thermal performance of liquid desiccant cooling cycle configurations
(Texas A&M University, 1995)
Five configurations of a 3-ton liquid desiccant cooling cycle were simulated and analyzed on a digital computer. Algebraic equations were developed for the dry bulbtemperatures and humidity ratios at different locations ...
Labyrinth stepped seal geometric optimization
(Texas A&M University, 1995)
High-speed rotating machinery poses a challenging problem to designers and engineers. Interference between rotating and stationary elements can result in excessive wear, decreased machine performance, or machine failure. ...
