Research Abstract

In this study as a cross-sectional study for fluid dynamics and chemical engineering, we performed the numerical simulations of supercritical fluid flows in a chemical reactor and evaluated the particle formation. The method for the calculation of thermophysical properties was proposed and the supercritical fluid flows are investigated by 2-D and 3-D computation. The area of particle formation is also investigated in the T-shaped channel and counter flow channel.
