Abstract

Transient flow structures and surface heat flux distribution of the interfered flow field induced by a backswept fin were obtained by Nano-tracer-based Planar Laser Scattering and temperature sensitive paints under M = 6. Meanwhile, the Reynolds-averaged Navier–Stokes equations with k-ω Shear-Stress Transport turbulence model were solved to simulate the flow field. The numerical results were compared and analyzed with the experimental results. Typical flow structures in interference areas of the swept fin were observed in experiment, including the detached bow shock wave, separation zone, thin boundary layer around the fin and horseshoe vortex, etc. The numerical results were in good agreement with flow visualization images. For heat flux distribution, the experiment observed the high heat flux region near the side of the fin leading edge caused by separated flow and the region with heat flux increase caused by bow shock. The numerical results of the heat flux caused by bow shock were pretty good, but the results of the high heat flux region near leading edge due to reattachment had much difference with the experimental results, which still need further improvement.
