Abstract
Low-Reynolds-number separation created by a steady adverse pressure gradient is usually considered to have a steady, large-scale structure, The computations of Lin & Pauley (1993), however, suggest that an unsteady large-scale structure controls the mechanism of separation bubble reattachment. The detailed unsteady separation structure of a low-Reynolds-number Eppler 387 airfoil was numerically studied using a time accurate artificial compressibility code. Periodic vortex shedding form the separation was observed in all cases studied. This paper studies the role of curvature on the unsteady separation structure by considering a flat plate geometry subject to the same surface inviscid pressure gradient as an Eppler 387 airfoil at 4° angle of attack.
