Electron emission thermal energy conversion
(University of Missouri--Columbia, 2010)
Electron emission from a surface can be achieved via two mechanisms: tunneling and thermionics. Converting thermal energy to electrical power using these mechanisms is achieved by generation of an electron current from the ...
An axisymmetric interfacial tracking model for melting-vaporization-resolidification in a thin metal film irradiated by pico to femtosecond pulse lasers
(University of Missouri--Columbia, 2010)
A two dimensional axisymmetric, interfacial tracking method is developed to model rapid melting and solidification of a free standing metal film subjected to an ultra-short laser pulse. Finite volume method is employed to ...
Analysis of oscillatory flow and heat transfer in an oscillating heat pipe
(University of Missouri--Columbia, 2010)
An advanced physical and theoretical model of a U-shaped minichannel - a building block of an Oscillating Heat Pipe (OHP) - has been developed step by step. a) The gravity and pressure loss at the bend are included in the ...
Molecular dynamics simulation of nanosintering processes
(University of Missouri--Columbia, 2010)
In this thesis, two scenarios of simulations are studied by molecular dynamics (MD) method. The first one will investigate the neck growth in the laser sintering of different-size gold (100) nanoparticles under different ...
Design and simulation analysis of MEMS parallel plate capacitor models for voltage conversion and power harvesting
(University of Missouri--Columbia, 2011)
In environment, unwanted and undamped vibrations are abundantly available which can be converted into electrical energy and used for energy harvesting. This paper contains the design, modeling and simulation results of ...
Fabrication and characterization of heat flux sensor using polymer derived ceramics
(University of Missouri--Columbia, 2011)
In this study, a free standing Resistance Temperature Detector (RTD) sensor made from Polymer Derived Ceramics (PDCs) for high temperature application (above 1000[degrees]C) is fabricated. A newly developed fabrication ...
Microfabrication and modeling of a tool for thermodynamic characterization of micro-samples
(University of Missouri--Columbia, 2012)
Cryopreservation is the process of preserving biological samples indefinitely at subzero temperatures. Successful cooling procedures have been developed for a limited number of cell types through an extensive amount of ...
Physical implications of characteristic speeds and waveforms of rails on elastic foundations
(University of Missouri--Columbia, 2012)
When a moving load is applied on an elastic rail with an elastic insulator, wave propagation can occur and become problematic after certain characteristic speeds are reached. Research of these waveforms and characteristic ...
Investigation of flow behavior inside ejector pumps using finite difference technique
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A complete numerical model has been developed to characterize the performance under different flow conditions. Finite Difference-based method was used ...
The Design and analysis of a HA/PLA pedicle screw for spinal fusion
(University of Missouri--Columbia, 2011)
Metallic pedicle screws have been widely used in the orthopaedic field to treat spinal diseases. Although spinal screws have improved over the last few decades, there is still sometimes a need for a second painful surgery ...
