A bulk-flow model of angled injection Lomakin bearings
(Texas A&M University, 2001)
A bulk-flow model for determination of the leakage and dynamic force characteristics of angled injection Lomakin bearings is presented. Zeroth- and first-order equations describe the equilibrium flow for a centered bearing ...
Experimental investigation of the condensation phenomenon in micro-grooved plates
(Texas A&M University, 2001)
The addition of micro-grooves to a condensing surface has been proposed with the aim of reducing the film thickness so that the condensation heat transfer coefficient is increased. Micro-grooves promote the removal of ...
Modeling and simulation of stable human locomotion using five degree-of-freedom gait model
(Texas A&M University, 2001)
Human locomotion involves a highly sophisticated and complex locomotive system. In order to understand how models of such system are built, it is useful to consider the meaning and implication of modeling and simulation ...
Experimental determination of dynamic force coefficients of a pocket damper seal at higher frequencies
(Texas A&M University, 2001)
Experimental results are presented for a two-bladed pocket damper seal (PDS) with eight partition walls on a high-speed test rig. The objective of these experiments is to measure damping coefficients, stiffness coefficients ...
Analysis of three-dimensional frames using shear-locking free beam elements based on the third-order shear-deformation theory
(Texas A&M University, 2001)
In the present research, space frames are studied by incorporating shear-locking-free beam finite element based on the third-order shear deformation theory. Currently, the beam element used in the analysis of frames is ...
Compliant mechanisms
(Texas A&M University, 2001)
The motivation for this work has been a variety of motions like navigation of pipelines, insertion operations in assembly, and gripping actions, which require the adaptation of the mechanism to the external constraints, ...
The effect of static and dynamic misalignment on ball bearing radial stiffness for variable axial preloads
(Texas A&M University, 2001)
The primary objective of the research project was to determine through rotordynamic computer modeling and experimental testing, the radial stiffness of a symmetric angular contact ball bearing for static and dynamic ...
Effect of doping in Bi-Pb-Sr-Ca-Cu-O superconductor composites
(Texas A&M University, 2001)
The goal of this thesis is to analyze the solid solubility limit of dopants in Bi-Pb-Sr-Ca-Cu-O superconductors. We have studied the effect of Mn doping Bi-Pb-Sr-Ca-Cu-O. The electrical resistivity and critical temperature ...
Analysis of a flexible polymeric film with imbedded micro heat pipes for spacecraft radiators
(Texas A&M University, 2001)
In response to the pursuit of interplanetary travel and a continuous human presence in space, there is increasing focus within the space industry on spacecraft designs that change configuration within the space environment. ...
Grain refinement in bulk pure tantalum using equal channel angular extrusion
(Texas A&M University, 2001)
For this study, the effectiveness of equal channel angular extrusion (ECAE) to improve the material properties and processing characteristics of vacuum arc remelted (VAR) pure tantalum was determined. The primary objectives ...
