Abstract Details

2003, MS, University of Cincinnati, Arts and Sciences : Physics.
The principle goal of the present research is to understand the process of crystal dendrite growth. The main interest is to map the concentration and the temperature profile in the environment surrounding a crystal that is growing in the melt, using algorithms developed in MATLAB. Using optical interferometric techniques, it is clear that during the growth of dendrite crystals, a concentration gradient in the solution drives molecules toward the crystal. This results in the release of heat that is fed back into the temperature field of the melt. Solidification proceeds by driving the liquid/solid interface through a temperature gradient, at a specific velocity. Recent experimental advances have made it possible to map the index of refraction of the solution in the vicinity of the growing crystal through Fourier Interferometric techniques. Of particular interest are the calculations of the temperature dependence on the index of refraction. These calculations make the mapping of a field surrounding the crystal possible using a Fast Fourier Transform Technique.
