Modeling of an induction plasma under transient turbulent flow conditions

The investigation of the role of turbulence for the transient behavior of the radio frequency induction plasma discharge by using a renormalization group (RNG) turbulence model was discussed. By comparing the predicted results with experimental observations under pulsed power conditions, the turbulence model was validated qualitatively. It was found that the transient behavior of the momentum and the plasma energy were governed by radial convection, while that of the turbulence was determined primarily by axial convection. The results show that the turbulence model predicted a more accurate transient behavior in terms of plasma volume and temperature than the laminar model does.
