Abstract:

A DIFFUSING-VORTEX METHOD, FOR SOLVING THE TWO-DIMENSIONAL INCOMPRESS NAVIER-STOKES EQUATION, WILL BE EXTENDED AND APPLIED TO THE EXTERNAL INCOMPRESSIBLE VISCOUS FLOW OVER A GENERALLY SMOOTH BLUNT BODY. THE NUMERICAL ADVANTAGES OVER OTHER LAGRANGIAN VORTEX METHODS WILL BE FURTHER DEMONSTRATEDBY REDUCING TOTAL CPU TIME AND BY AVOIDING CUT-OFF PROCEDURES. THE NEW APPROACH WHICH IS AN APPROXIMATE EXPRESSION OF THE GREEN'S FUNCTION OF THE DIFFUSION EQUATION, WILL BE CONSTRUCTED FOR A GENERAL TWO-DIMENSIONAL SMOOTH CONTOUR AT A HIGH REYNOLDS NUMBER. A BENCHMARK CASE,THE CYLINDER PROBLEM WILL BE USED TO EXAMINE THE ACCURACY OF THE CODE AND THE EFFECT OF SPATIAL MESH LENGTH AND TIME STEP LENGTH ON COMPUTATIONAL RESULTS.
