| Popis: | The paper is dedicated to the numerical simulation of two-dimensional viscous incompressible flow. The Viscous Vortex Domains method is considered, which is one of the modifications of Lagrangian vortex methods. This method is implemented in the open-source VM2D code, which developes by the authors. Model problems of exter- nal and internal flow simulation are considered for VM2D testing. For the problem of the flow simulation around two closely spaced circular cylinders, VM2D is compared to OpenFOAM in terms of computational efficiency. As the internal flow problem the flow in a channel with a backward-facing step is considered. For both problems, the results obtained in VM2D are in good agreement with the results of other researchers. |
