Development of a frequency doubled high powered laser diode end-pumped Nd:YVO₄/LBO laser
(Texas A&M University, 2003)
The development of a high power solid state laser poses a serious non-trivial task. Several different elements combine to form this complex quantum device. Each of the elements of the laser receives sufficient description ...
High pressure testing of see-through labyrinth seals
(Texas A&M University, 2003)
Detailed results are presented for teeth-on-stator labyrinth seals tested under high pressure of 70 bar-a (1015 psi-a) and 52 bar-a (754 psi-a) in the centered position. The seals were tested at pressure ratios of 0.52, ...
Rotordynamic evaluation of hybrid damper seals with metal mesh elements
(Texas A&M University, 2003)
Metal mesh hybrid damper seals (MHS) were proposed to be an alternative for brush hybrid pocket damper seals (PDS) in turbomachinery. The metal mesh hybrid damper seal is a hybrid of the pocket damper seal and the metal ...
Experimental study of the effects of wakes on separation in low pressure turbine flow
(Texas A&M University, 2003)
The present study, which is the first of a series of investigations dealing with specific issues of low pressure turbine (LPT) boundary layer aerodynamics, is aimed at providing a detailed unsteady boundary flow ...
Optimal internal combustion engine tuning utilizing perturbation/correlation
(Texas A&M University, 2003)
This thesis addresses the application of the perturbation/correlation method to optimizing the torque output of internal combustion engines. This application was inspired by observations of the limitations in current ...
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 investigation of heat transfer in narrow, rectangular cooling channels with pin-fins
(Texas A&M University, 2003)
The effect of rotation on smooth narrow rectangular channels and narrow rectangular channels with pin-fins is investigated in this study. Pin-fins are commonly used in the narrow sections within the trailing edge of the ...
Kinematic conditioning augmentation to haptic interface for teleoperation
(Texas A&M University, 2003)
A solution is proposed for the kinematic conditioning problem in teleoperation. The proposed solution helps the operator in understanding the kinematic conditioning of the slave manipulator with the help of haptic interface. ...
Heat transfer in rotating rectangular channels (AR=4:1) with V-shaped and angled rib turbulators with and without gaps
(Texas A&M University, 2003)
An experimental study was performed to measure the regionally averaged heat transfer distributions in a rotating ribbed channel with an aspect ratio of 4:1. The Reynolds number, based on a hydraulic diameter, varies from ...
