Estimating cancellous bone properties of the rat from mechanical testing of the femoral neck
(Texas A&M University, 1998)
The rat has become a popular model for studying the aphics. effects of ovariectomy on bone properties. Testing the femoral neck has likewise become more popular in an attempt to estimate mechanical properties of cancellous ...
Experimental shellside flow visualization in a shell and tube heat exchanger
(Texas A&M University, 1998)
Shell and tube heat exchangers are an extremely effective and mechanically feasible method of transferring thermal energy between two fluids. There is great demand for effective design methods capable of producing highly ...
Manufacturing and performance of ceramic/metal matrix composite electrical discharge machining electrodes
(Texas A&M University, 1998)
The manufacturing and performance of ceramic/metal matrix composite (cermet) electrical discharge machining (EDM) electrodes have been investigated. The processing techniques necessary for creating TiB2/Cu, TaC/Cu, TaC/Cu(s), ...
The effect of equal channel angular extrusion on the microstructure and mechanical properties of AISI 1552, AISI 4340, and A2 tool steels
(Texas A&M University, 1998)
In this investigation, Austenitized AISI 4340 and A2 tool steel were ausformed using ECAE as a sole deformation mechanism. In addition, AISI 1552 steel was deformed by ECAE. The effect of deformation on hardness, tensile ...
A visualization comparison of convective flow boiling heat transfer augmentation devices
(Texas A&M University, 1998)
The qualitative effects of inset-table heat transfer phics. augmentation devices on vertical in-tube convective flow boiling flow regimes, transition mechanisms, and heat transfer are presented in this study. Three twisted ...
Methods for testing the strength of cancellous bone and tested method effects on cortical bone in the ovariectomized rat
(Texas A&M University, 1998)
In this study, two mechanical testing procedures were developed to test the strength of cancellous bone from the proximal tibia of the rat, the "punch method" and the "whole slice method". These were used to quantify the ...
Electrical resistance measurements of highly inhibited SiC coated carbon-carbon laminates
(Texas A&M University, 1998)
The effect of oxidation damage at 900'C of highly inhibited, SiC coated carbon-carbon laminates on shear modulus, mass loss, and electrical resistance are studied. The approach taken enabled the interpretation of the shear ...
Enhancement of pool boiling heat transfer with electrohydrodynamics and its fundamental study
(Texas A&M University, 1998)
The enhancement of heat transfer in the realm of pool boiling refrigerants, using the concepts of electrohydrodynamics(EHD), has been actively researched in the past decade. This research aims at studying the effect of EHD ...
The design of a test rig for the identification of dynamic coefficients of a high temperature magnetic bearing
(Texas A&M University, 1998)
This thesis is a report on the research and Micrographics. development to design a test rig for the identification of the dynamic coefficients of a radial magnetic bearing. The test rig development is intended for dynamic ...
Numerical study of flow and heat transfer in 3D serpentine channels using colocated grids
(Texas A&M University, 1998)
channels, which have applications in heat-exchangers, were studied. A finite-volume code in FORTRAN was developed to solve this problem. Modules were made for generating rids in the domain, for valving the flow velocities ...
