Abstract

In the present paper the flowfield around a delta wing partially embedded in the wake of a bursted vortex is numerically studied at M*&#610.4. The simulation is carried out solving the Euler equations on two structured grids of about 2.3 million points and 300000 points respectively. Due to the lack of experimental results, special emphasis is put on the analysis of the effect of grid fineness on the wake-flow. The present investigation indicates that the spiraling flow of a vortex continues after breakdown with a swirl velocity comparable to that of a non-bursted vortex generated at lower angles of attack and hence interference effects coming from its wake persist long downstream.
