Abstract

This paper presents a comparison between experimental data and computational results for the linear plasma synthetic jet actuator (L-PSJA). The L-PSJA configuration consists of two exposed electrode strips separated by an embedded electrode, similar to two linear dielectric barrier discharge actuators being placed back-to-back. Experiments have shown that the resulting flowfield is similar to a surface jet, and by pulsing the power to the electrodes an oscillatory flowfield similar to a synthetic jet can be produced. The computational model used for the plasma forcing is the Suzen{Huang plasma actuator model which has been placed in an imcompressible, unstructured grid code. Both quiescent and cross-flow conditions are simulated and compared to the available experimental measurements. The objective is to assess the capabilities of the plasma actuator model for the L-PSJA configuration.
