J0101-1-2 Numerical Simulation of Liquid and Supercritical-fluid Flows with Phase Change

Abstract

The supercritical-fluids simulator (SFS) developed by our group is applied to turbulent flows near critical point with heat transfer. In SFS, a numerical method based on the preconditioning method coupled with the PROPATH is used. In this paper, turbulent flows of supercritical carbon dioxide in a tube are calculated in several temperature conditions. The calculated results are compared with each other and the heat transfer coefficients are compared with the existing experimental results.
