Modeling of the Heat Interface of a Plasma Actuator

We simulated a one-dimensional plasma actuator (PA) with a dielectric layer by using the electric potential equation, the electron and ion density conservation equations, and the enthalpy equation. We then derived the correlation of electron and ion density using the Navier Stokes equation and the enthalpy equation and modeled it using the Reynolds decomposition. We also made an energy model interpretation of the differential system at the initial state. The computation results show that the gradient of the correlation of the electron density and electric field was nearly constant in space; therefore, gradient transport modeling can be applied. An experiment conducted to confirm the existence of the phenomena successfully revealed the intermittent jets. We used our experimental configuration to compute two-dimensional flows, and we obtained an induced periodic jet flow. We also observed cylindrical waves emitted from the trailing edge of the anode. We have successfully extracted fine structures of the PA, including its aero-acoustic property
