The effect of injection hole geometry on flat plate film cooling and heat transfer
(Texas A&M University, 1994)
Larvae of the diamondback moth Plutella xylostella (L) were bioassayed with a leaf-dip technique for susceptibility to formulated permethrin and methamidophos at four temperatures (10, 20, 25, and 350C) . Permethrin ...
Effect of film hole location on heat transfer coefficient and film effectiveness of a gas turbine blade
(Texas A&M University, 1994)
Experiments were performed to study the effect of film hole location on local heat transfer coefficient and film effectiveness distributions of a turbine blade model with air (D.R. = 1.0) and C02 (D.R. = 1.52) film injection. ...
Effect of environmental exposure on the stiffness and energy loss properties of nitrile elastomers
(Texas A&M University, 1994)
Elastomers play an important role in today's society. Elastomers, in many applications, are exposed to elevated temperatures and environments that can alter material properties. All to often the elastomer itself may be ...

Electrical Energy Monitoring in an Industrial Plant
(Texas A&M University, 1994)
This thesis presents an investigation into the actual electrical energy and demand use of a large metal fabrication facility located in Houston, Texas. Plant selection and the monitoring system are covered. The influence ...
The design, construction, and calibration of a dynamometer used to measure forces applied by a magnetic bearing to a rotating shaft
(Texas A&M University, 1994)
A force measurement dynamometer has been constructed which will be the primary instrument used to measure the dynamic forces applied by a magnetic bearing to a rotating shaft. The dynamometer consists of two force measurement ...
An empirical model for the mean-velocity profiles of a turbulent boundary layer under the effects of surface curvature
(Texas A&M University, 1994)
An empirical model has been developed to predict the mean-velocity profile of a turbulent boundary layer under the influence of surface curvature. The model proposed is able to determine the profiles for both a convex and ...
Effect of recess pressure ratio on the characteristics of a hybrid bearing
(Texas A&M University, 1994)
Hybrid (Combination Hydrostatic and Hydrodynamic) bearings have shown good properties in testing and in consideration for applications such as the Space Shuttle Main Engine High Pressure Oxygen Turbopump. However, properties ...
Improvements and applications of non-contacting interferometry
(Texas A&M University, 1994)
The research described in this thesis involves the development and application of a two channel, fiber optic, interferometer. The existing interferometer system consists of an Argon laser, single mode fiber, and an array ...
Open loop control for six degree of freedom alignment using phase plane methods
(Texas A&M University, 1994)
This thesis will discuss how the Targeting and Reflective Alignment Concept (TRAC), developed by Lockheed for Johnson Space Center, is enhanced by converting it into an automated process. A brief discussion outlining the ...
