VORTICITY-MAINTENANCE TECHNIQUE FOR USE IN NUMERICAL SIMULATION OF INCOMPRESSIBLE VORTEX FLOW FIELD

摘要

The present invention relates a numerical method to simulate the incompressible wing-tip vortex flows. This method is called Vorticity-Refinement, which refines the added vorticity as two different forms of force multiplied by two different factors to counteract the numerical diffusions in the numerical solutions by utilizing the high-order spatial discretization and improving the stability and convergence of the governing equations for incompressible flows.
