Аннотация
Scientific visualization is certainly a very important and useful area of research, providing utilities not only for visualization, but also for the investigation and analysis of the data obtained. Herewith, the data can be both experimental and numerical.
This paper demonstrates the application of scientific visualization and identification methods of vortex structures to the problem of the supersonic tip vortex propagation in the incoming flow disturbed by an energy source. The undisturbed incoming flow Mach number was M∞ = 3, the wing attack angle was 10°. Numerical data were obtained in the region of 30 wing chords downstream from the wing axis.
At the same time, significant differences are shown between the results of applying classical visualization methods, such as λ2 and, Q, and the third-generation Liutex method to the considered problem for visualization and identification of the tip vortex. Moreover, according to the results of further research, it seems that a more truthful picture of the flow is given by the method of the third generation while used classical methods give false additional vortex data.
Numerical simulations were performed with the developed ARES software package for modeling 3D turbulent flows on high-performance computer systems on the hybrid supercomputer system K-60 at the Keldysh Institute of Applied Mathematics of the Russian Academy of Sciences. 112 processors were used for perform the simulations.
Ключевые слова: supersonic flow, energy wake, tip vortex identification, scientific visualization tools.
