  • G0510301 Numerical Method Simulating Supercritical-fluid Flows based on Cartesian Mesh Method coupled with Meshless Method

抄録

The mixing flow of supercritical water and liquid water in a T-shaped channel is simulated using the Cartesian mesh method coupled with a least-square meshless method. In the present method, the Supercritical-fluids Simulator (SFS) is coupled with the Building-Cube Method (BCM), because of its simplicity and efficiency; and a meshless method is further applied to the wall boundary treatment because of its flexibility. Two test cases are conducted: First, a simple experimental validation is proposed to show the effectiveness of the present method; then, the numerical validation is also proposed, and the numerical results by the immersed boundary method are used for comparison, the advantage of the meshless method over the immersed boundary method is clearly shown. The present method is proved to be a promising tool for 2-D practical supercritical-fluid flow simulations.
