Mechanical Properties And Corrosion Resistance Of Ni-Sic Nano Composite Coatings On 2024-T3 Aluminum, Amit Jain
Mechanical Properties And Corrosion Resistance Of Ni-Sic Nano Composite Coatings On 2024-T3 Aluminum, Amit Jain
Masters Theses
Coatings of nickel with and without silicon carbide nano-particles were carried out on 2024-T3 aluminum alloy by the electrochemical process. The size of the silicon carbide particles was less than 50nm. Nickel coatings were done using a nickel sulfamate bath maintained at a constant temperature of 50° ± 5° C. Tensile specimens were prepared and studied to determine the Young's modulus of bare aluminum, with nickel coatings and with composite nickel and silicon carbide coatings. Wear samples of 1 inch2 (6.45cm2) were prepared and studied for wear resistance. The residual stress measurements were done by the hole …
Effect Of Loading Frequency On Intervertebral Disc Cells., Kristen Nicole Loveless
Effect Of Loading Frequency On Intervertebral Disc Cells., Kristen Nicole Loveless
Masters Theses
Cells of the intervertebral disc have a limited capacity for matrix repair and may contribute to the onset and progression of degenerative disc changes. Disc degeneration contributes to declining nutrition, loss of viable cells, cell senescence, post-translational modification of matrix proteins, accumulation of degraded matrix molecules, and fatigue failure of the matrix. During daily activities intervertebral discs are exposed to oscillatory hydrostatic loads. It is known that dynamic loads with critical frequencies close to that of the human spine resonant frequency (4-8 Hz) have a destructive effect on disc tissue properties. Whether this destructive effect is purely mechanical due to …
Modeling Of Circulation Zone And Shear Layers In Coaxial Injectors, Clayton Andrew White
Modeling Of Circulation Zone And Shear Layers In Coaxial Injectors, Clayton Andrew White
Masters Theses
Gaseous/gaseous hydrogen oxygen shear coaxial injectors were modeled to investigate grid parameters affecting solution and to determine if a steady state solution might exist if only one circulation zone was present. The General Equation Mesh Solver (GEMS), which implements the Reynolds Averaged Navier-Stokes equations with the k-ω turbulence model, was used to conduct the study. The Gambit grid generator was used to construct computational grids. Different grids were compared in a search for the optimum configuration while residual levels were monitored in search of a steady state solution.
The Development And Verification Of Three Matlab Analysis Applications Programmed Specifically For Engage Team Projects., Jonathan W. Huber
The Development And Verification Of Three Matlab Analysis Applications Programmed Specifically For Engage Team Projects., Jonathan W. Huber
Masters Theses
This thesis outlines the development of three analysis applications for use in the freshmen Engineering Fundamentals Program (engage) at the University of Tennessee. Engage teaches freshmen engineering mechanics concepts through a set of integrated components including Lecture, Analysis and Skills, Problem Session, Physical Homework, and Team Projects. Presently, the students have limited access to any software analysis tools to aid the design process. The students have little experience writing the types of complex programs needed to analyze a particular project. Even more, they do not have the time. The applications provide a means for the students to perform an accurate …
A Study On The Prediction Of Viscosity With The Use Of Numerical Simulation Software, Brian Robinson
A Study On The Prediction Of Viscosity With The Use Of Numerical Simulation Software, Brian Robinson
Masters Theses
A study was undertaken to numerically simulate the flow of highly viscous fluid. Simulating a highly viscous flow within a parallel plate plastometer will hopefully begin to bridge the gaps in the current knowledge of these viscous models. The modeling of this flow was performed using the canned code FiDAP from Fluent Inc. The results are compared with the analytical results calculated by NASA Marshall researchers.
A Study Of The Electron Beam Scattering Under Various Gaseous Environment, Jing He
A Study Of The Electron Beam Scattering Under Various Gaseous Environment, Jing He
Masters Theses
There are three objectives in this work: to experimentally measure the profiles of electron beams scattered by interaction with a gas, to measure total scattering cross-sections for gases and to apply the cross-section data in a suitable Monte Carlo simulation to predict beam scattering profiles for comparison with experiment.
The experimentally measured profiles cover a wide range of intensity variation. There are two evidenced regions: an inner region and an outer skirt corresponding to inelastic (small angle) and elastic scattering respectively are appeared. These profiles use the planar p-n junction gives us an overall look at the electron beam spreading, …
