Numerical solution of 2-D incompressible viscous flow with high order compact scheme using domain decomposition and matched method

摘要

This paper presents a high-accuratcy method for solving 2-D incompressible viscous N-S equations in tensor forms. A domain decomposition method was used to divide the computational domain into several regular blocks with the overlapping grid in order to transfer data between sub-domains and to remove numerical singularity caused by domain decom- position. Using the method and algorithm presented above, the flow passing an ellipse was computed and the formation and evolution of the vortex shedding was successfully simula- ted.
