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 ... -
A comprehensive model for energy transport and ablation of metal films induced by ultrashort pulsed lasers
(University of Missouri--Columbia, 2012)A comprehensive laser material ablation model was developed to describe energy transport, ultrafast phase changes, and material ablation of metal films irradiated by ultrashort laser pulses. The two optical models were ... -
Dynamic simulation of particulate and molecular systems
(University of Missouri--Columbia, 2011)Granular packing of millimeter-scale and micrometer-scale particles with three different size distributions (monosize, bimodal and Gaussian) are studied using the Distinct Element Method (DEM). The dissipative forces ... -
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°C) is fabricated. A newly developed fabrication method to ... -
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 ...
