| Summary: | Simulation of hydrodynamic phenomena associated with flow around movable deformable bodies is an actual engineering task of various technical problems. This article describes the method of vortex loops, which allows to simulate the flow around bodies without the need to preset the lines of vorticity retreat. Verification of the technique on the experimental data on the flow past the wing and the sphere is given. The accuracy is shown sufficient for application of the program and methodology in engineering applications. Conclusions are made about the possibility of transition to mobile and deformable bodies. The program is implemented in C ++ with the use of the MPI library to organize the transfer of data in parallel calculations. |
