Toward hybrid simulation of flow generation in DBD plasma actuator.

We developed a particle code based on the PIC-MCC method and a plasma fluid code solving drift-diffusion equations. Fluid simulation produces a streamer-type discharge for a positively biased input applied to the exposed electrode against to the buried electrode as obtained in particle simulation. However, we found differences in micro-discharge formation around the exposed electrode between the results of the two codes, suggesting that a hybrid approach based on particle and fluid models may be needed for a long-term precise simulation. Our hybrid code and perspective models are presented for reliably predicting the entire dynamics from micro-discharge to flow generation in a DBD plasma actuator. [ABSTRACT FROM AUTHOR]
