APPLICATION OF A COMPLETE MULTI-NETWORK METHOD FOR SOLVING THE PROBLEM OF FLOWS AROUND SPHERE
R. K. Narimanov · Eurasian Physical Technical Journal · 2019
Using the example of a numerical solution of the classical problem of a viscous flow past a sphere, the efficiency of using the multigrid method was compared with direct calculations. Various difference schemes are considered. It's shown that to go from grid to grid, for a vortex equation, it is necessary to use a 9-point pattern. For different Reynolds numbers the resistance coefficient to friction had been calculated. The limit on the Reynolds number when using the multigrid method is noted.
