A numerical analysis of the impact of gas pressure and dielectric material on the generation of body force in an air gas plasma actuator

Abstract

Impact of dielectric materials on plasma characteristics and body force in an SDBD plasma actuator.• The rate of species generation in the plasma actuator is significantly influenced by the dielectric substance.• Changing the dielectric material does not make a significant difference in electron temperature.• Electron density changes in response to the change in the dielectric material.• Ion density is affected by the dielectric material, with mica having the highest ion density and PTFE having the lowest.
