This work is devoted to the application of vortex structure identification methods for two counter-rotating wingtip vortices in a supersonic flow. The λ2 criterion and the method of maximum vorticity were used for detection vortex core lines and visualization of vortex sheet and rope. Computational model based on the URANS equations with SA turbulence model was applied. Numerical simulations were performed on the hybrid supercomputing system K-60 at the Keldysh Institute of Applied Mathematics RAS using the developed software package ARES for 3D turbulent flows modeling on high performance computing systems.

Scientific visualization is an important stage of research. It is intended to provide postprocessing analysis tools for presenting the results obtained numerically and/or experimentally. This is especially topical with regard to the increasing volume of processed data associated with the productive capacity growth of computing systems.In this work two scientific visualization methods were applied to recognize flow parameters obtained by numerical simulation of counter-rotating supersonic vortex pair interaction: the λ2-method and maximum vorticity method.The results of their application are compared. The numerical data was obtained by a computational model based on the URANS equations with SA turbulence model. Numerical simulations were performed on the hybrid supercomputing system K-60 at the Keldysh Institute of Applied Mathematics RAS. The main simulation results are presented and analyzed.
