Abstract

An experimental study of sweeping jet (SWJ) actuators is conducted to determine the jet oscillation frequency which is a key parameter for an effective flow control. The static pressure is measured on the upper feedback channel using Kulite XTL-140 high-frequency pressure transducers for eight different mass flow rates for the baseline geometry. Scaling effect on the oscillation frequency is studied using half-and double-sized SWJ actuators. The results reveal a linear trend of the oscillating jet frequency versus the mass flow rate for all of the geometries. Moreover, two-dimensional Unsteady Reynolds-Averaged Navier-Stokes (URANS) simulations have been performed. Comparison of experimental and numerical results are presented. The smaller geometry creates higher frequencies for the same mass flow rate. However, the Strouhal number is constant for all of the sizes.
