The effect of a new damper seal on rotordynamics
(Texas A&M University, 1995)
An existing rotordynamic test apparatus is modified for a new type of gas damper seal. Experimental results including coastdowns, rap tests and leakage from the gas damper seal are presented along with comparison tests of ...
Planar visualization of phase objects using a focusing schlieren technique
(Texas A&M University, 1998)
A focusing schlieren technique has been designed and phics. constructed to examine planar images of optically thin phase objects including high-speed gas jets and flames. The conventional schlieren technique is a highly ...
Commanding lateral acceleration: a natural paradigm for automobile steering
(Texas A&M University, 1998)
This thesis describes a joystick automobile steering phics. controller which allows the driver to command the lateral acceleration of the vehicle directly, as opposed to controlling the front tire angle. The purpose of the ...
A comparison of the static and dynamic characteristics of straight-bore and convergent tapered-bore honeycomb annular gas seals
(Texas A&M University, 2000)
Results are presented from tests conducted with straight-bore and convergent tapered-bore honeycomb annular gas seals. The test seals had a 114.3 mm bore with an L/D = 0.75 and a nominal radial clearance of 0.19 mm. The ...
The effect of moisture on a glass/epoxy composite
(Texas A&M University, 1996)
Research was done to determine the effect of moisture on the transverse tensile strength and the interfacial shear strength of a glass/epoxy composite. Specimens with two different fiber sizings, one epoxy compatible and ...
A parametric study of thermomechanical behavior of functionally gradient materials
(Texas A&M University, 1996)
The dynamic thermoelastic response of functionally gradient cylinders and plates is studied. Thermomechanical coupling is significant in these materials when they are used in high temperature applications, and hence, the ...
The constitutive modeling of nitrile elastomers
(Texas A&M University, 1996)
A method for modeling the transient stress relaxation and creep behavior of acrylonitrile butadiene rubber has been developed. The behavior of the material is characterized through the use of transient stress relaxation ...
Local heat transfer distribution in a two-pass trapezoidal channel with a 180 [degree] turn via transient liquid crystal technique
(Texas A&M University, 1996)
This experimental research investigates the heat transfer characteristics of air flows in serpentine cooling channels in stationary stator blades of gas turbines. The internal cooling channels are modeled as a smooth ...
Development and use of an interactive computer simulation for generalized technical and economic assessments of cogeneration systems
(Texas A&M University, 1997)
The development and use of a computer simulation program incorporating an interactive spreadsheet software package to evaluate the technical and economic feasibility of cogeneration systems is described. Three hypothetical ...
Synthesis of reduced order prefilters for multivariable tracking
(Texas A&M University, 1997)
A primary disadvantage of using an internal model to achieve multivariable tracking is the high order of the internal model. In situations where it is known that each output is to track only its associated reference input, ...
