Plasma Modelling for CFD: Perspectives and Retrospectives
The interaction between non-thermal plasmas and turbulent flows (as occurs in plasma flow control, plasma-assisted combustion, plasma medicine, or plasma-based fuel reforming) has been so far a major challenge to simulate numerically due to the large variation in physical time scales involved: while electrons travel at velocities as high as millions of meters per second within the sheaths, neutrals and ions travel at velocities 4-6 orders of magnitude lower. This large discrepancy between the time scales has made it difficult to incorporate detailed plasma models within CFD codes for fluid flow. We discuss recent advances in computational plasmadynamics that overcome this hurdle and make addition of a detailed plasma model to a CFD code relatively trouble-free.
