The pressure problem in the stochastic vortex blob method
Institute of Aeronautics and Applied Mechanics Warsaw University of Technology Nowowiejska 22/24, 00-665 Warsaw, Poland
The paper deals with the problem of recovering pressure from the given vorticity and velocity fields. Both fields result from the stochastic vortex-blob simulation of the viscous incompressible flow. The vorticity field is a discontinuous function. The method is presented here to find pressure as a solution to the variational problem which forms the weak version of the momentum equation. No explicit boundary condition for pressure are required and no derivatives of vorticity have to be calculated in this approach.
