A numerical and experimental study of tangential jet blowing appliedto bodies at high angles of attack

Abstract

The effects of tangential jet blowing on the vortical structures developing about the fuselage of a missile or aircraft at high angle of attack are investigated numerically and experimentally. Computations are carried out for fully laminar and fully turbulent flows, and the results are compared with flow visualization data. It is shown that turbulent computations are more accurate in describing the flow behavior. The actuator plane method is shown to be sufficiently accurate in modeling the essential flow physics of a tangential jet.
