Abstract
Numerical investigation of the flow around rectangular wings placed near the cavity is studied by the immersed boundary method with body force type. Two cases of angle of attack, θ=90° and θ=60°, were tested with Re=1000 based on the width of the rectangular wing and inlet speed. In the case of θ=90°, the asymmetric vortical structures grow at the downstream, and the backflow region is found behind the wing. In the case of θ=60°, however, vortical structures become weakened and backflow region at the back of the wing disappears mostly due to the blowing from the cavity.
