Résumé

The effect of the dielectric barrier discharge (DBD) plasma-actuator on the flow development towards its appropriate control, concerning for instance transition delay, drag reduction and flow separation delay or its complete elimination, is accounted for through a relevant body force representing a source term in the equation of motion. However, according to authors' awareness, in none of the plasma-actuated flow control applications published hitherto the specif c plasma-related turbulence production is taken into account in the equations governing the turbulence quantities. This motivated the present work which is concerned with the computational modelling of the Reynolds stress production term originating from a plasma actuator.
