Description

Physical Vapor Transport is a manufacturing process used to produce single crystals of semiconductor materials such as mercurous chloride (Hg2Cl2). In the past this time-varying process has been studied with numerical simulation by assuming axi-symmetric three dimensional flow or modeling the flow in two dimensions only. It is generally agreed that neither of these methods accurately represent the true behavior of the process. The purpose of this research was to extend the asymmetric model to three dimensions. The resulting data was then visualized and analyzed. The simulations were performed with a commercially available computational fluid dynamics software package called FIDAP on the 138-processor "supercomputer" here at Minnesota State University, Mankato. The visualization tool used was Tecplot 360. The results have shown that the flowfield is indeed asymmetric and cannot be characterized by a two dimensional simplification.
