Experimental evaluation of pocket damper seals with brush seal elements
(Texas A&M University, 2000)
The brush hybrid pocket damper seal (BHS) has been proposed to replace a labyrinth seal or pocket damper seal (PDS) in a turbomachine when damping is desired without increased leakage. The BHS and brush-only seal are ...
Hybrid delayed/undelayed LQG compensation
(Texas A&M University, 2002)
The problem of regulating the output of a stochastically perturbed finite dimensional linear time invariant continuous-time system by feedback control is considered. The regulation objectives are expressed in terms of a ...
Demonstration of triple pump coherent anti-Stokes Raman scattering in a jet diffusion flame
(Texas A&M University, 2002)
Three pulsed narrow band pump sources (a frequency doubled pulsed Nd-YAG, and two narrow band dye lasers) and a broad-band Stokes laser source are used to demonstrate triple pump coherent anti-Stokes Raman scattering in a ...
Maximizing tolerable disturbances in a coupled structural system using a QFT-like method
(Texas A&M University, 2000)
This thesis concentrates on developing an active control strategy that can be used to attenuate the far-field acoustic signature of a submarine by attenuating the vibration of its hull. The main goal of this thesis is to ...
A study on the effect of inlet turbulence on gas mixing for single point aerosol sampling
(Texas A&M University, 2001)
The efficiency of certain mixing elements in achieving conditions suited for single point sampling is evaluated. Experimental measurements of velocity and tracer gas concentration are taken to determine the same. Readings ...
A Study of Industrial Equipment Energy Use and Demand Control
(Texas A&M University, 2001)
Demand and duty factors were measured for selected equipment [air compressors, electric furnaces, injection-molding machines, a welder, a granulator (plastics grinder), a sheet metal press and brake, a lathe, a process ...
A study of the effect of boundary conditions and drag force on the diffusion of a Newtonian fluid through a non-linearly elastic solid
(Texas A&M University, 2002)
In this work, we investigate the problem of diffusion of a Newtonian fluid through a non-linearly elastic solid undergoing large deformations, within the framework of mixture theory. The aim is to delineate the effect of ...
Measurements of wall heat (mass) transfer for flow through blockages with round and square holes in a wide rectangular channel
(Texas A&M University, 2002)
Naphthalene sublimation and pressure measurement experiments were conducted to study heat (mass) transfer enhancement by blockages with staggered round and square holes for turbulent air flows through the holes in the ...
A phenomenological model for rarefied gas flows in thin film slider bearings
(Texas A&M University, 2002)
We analyze rarefied gas flows in lubricating films that form between the read/write head and rotating recording medium in computer hard drives. A modified slip-corrected Reynolds lubrication equation is derived for arbitrary ...
The study and characterization of the major flow through rectangular slit virtual impactor
(Texas A&M University, 2002)
The major flow through a rectangular slit virtual impactor was experimentally studied. The impactor was a two-dimensional rectangular slit dichotomous sampler. A series of experiments were performed using monodisperse ...
