Induced Flow Simulation by Means of Low-Temperature Plasma via a Multi-Components Boltzmann Method

Abstract:

A multi-components lattice Boltzmann method for weakly ionized plasma is employed in our simulation. A term to describe the plasma ionization, recombination and charge attachment has been added in the equations. An induced flow by surface dielectric barrier discharge plasma actuator is simulated. The distributions of electrons, positive ions, and negative ions near the solid wall were obtained. It was found that the charge mainly distribute on the on the dielectric surface upper the embedded electrode. The flow field and velocity profile near the surface was obtained. It was found the plasma actuators can significantly increase the velocity of an induced flow at the boundary layer.
