Abstract
This paper presents results of a parametric investigation on leading-edge vortex (LEV) trajectory and separation control sensitivity to a recessed discrete jet’s location, orientation, and size when actuated at momentum coefficient ≤ 0.02 on a rounded leading-edge, 45 degree swept, cropped delta wing in incompressible flow. The study determined that the maximum spanwise displacement of the LEV separation point, and thus maximum recovery of the attached flow region, required minimum momentum and mass flow when the jet was located immediately downstream of and near-aligned with the laminar separation bubble reattachment line. Once optimally placed, the spanwise extent of LEV separation displacement is a function of momentum and mass flow, and greater momentum is required to achieve a prescribed spanwise displacement at greater angles of attack.
