Visualization of the Tip Vortex Influenced by Supersonic Incoming Flow Disturbances
Abstract:
The paper presents the analysis results of a supersonic tip vortex propagation when the incoming flow is disturbed by an energy source in front of the wing generator using the methods of scientific visualization. The energy source center is located upstream from the wing generator angle formed by its leading and tip edges. The used wing is straight, rectangular in plan with sharp leading, tip and trailing edges, located at an angle of 10 degrees to the incoming flow with Mach number M? = 3. Numerical data were obtained in an area exceeding 30 wing chords downstream from the wing axis. Numerical model based on URANS equations with the hybrid method DES based on the turbulence model SA was used. Numerical simulations were carried out on the K-60 hybrid supercomputer system at the Keldysh Institute of Applied Mathematics RAS. Scientific visualization is performed both by widespread traditional vortex identification methods ?2 and Q, and by the method of the latest generation Liutex, which is free from shear and compressive components of the strain rate tensor by its construction. Significant differences in the applying results of the classical scientific visualization methods and the latest generation visualization method to the vortex identification in considered problem are shown.
