Abstract

A robust and flexible numerical framework was developed for modelling of dielectric-barrier discharge applicable to plasma actuated flow control. In OpenFOAM, a solver was built which solves convection-diffusion equations for ionized species coupled to Gauss’ law for electrostatics and includes a chemical model to account for the various chemical reactions taking place in non-equilibrium cold plasma. The framework relies on a predictor-corrector method and was verified and qualitatively validated in 1D using a volumetric cathode-fall glow discharge case. Quantitative validation in 1D and extension to 2D was recommended for future work as steps towards increased capability of the solver.
