Title: Modified Split-Potential Model for Modeling the Effect of DBD Plasma Actuators in High Altitude Flow Control
Issue Date: 2014
Abstract: Surface DBD plasma actuators are novel means of actively controlling flow. They have shown promisingability in reducing drag, postponing transition from laminar to turbulent flow, suppression of separation,noise reduction and enhancement of mixing in different applications. The CFD simulation of the effect ofplasma actuator in such kind of applications could provide more information, and insight, for optimization and design of close looped flow control systems. However, the fluid models for simulating theformation of the plasma and its effect are computationally expensive such that, although they providemore detailed information about the physics related to the formation plasma, they are still not viable tobe used in large scale CFD simulations. In this paper, we present the modified version of a simpler modelthat predicts the thrust generated by the plasma actuator with acceptable accuracy and can be easilyincorporated in CFD calculations. This model is also free of empirical fitting parameters, being based onpure flow physics scaling.
