Abstract

The Flow Simulation Methodology (FSM) is evaluated for the case of a separated flow subject to control by oscillatory forcing. The geometry chosen is the hump geometry from the NASA Langley CFD Validation Workshop 2004. In addition to the FSM, Direct Numerical Simulation (DNS) results are also presented. Simulation data for the uncontrolled flow, control by steady suction, and control by unsteady forcing all agree very well with the experimental data for both DNS and FSM. In addition, the ability of the FSM to produce accurate results over a wide variety of model Alter widths is demonstrated. Finally, the relative strengths of the two approaches (FSM and DNS) are compared.
