Abstract

The present study has been conducted to clarify the magnetic control characteristics of a particle-laden compressible plasma jet impinging on a substrate for the improvement of a low-pressure plasma spraying process and its controllable optimization. The plasma jet is described by an Eulerian approach and each injected particle is described by a Lagrangian approach, respectively, taking into account the compressible effect, variable transport properties, and plasma-particle interactions, coupled with the Maxwell's equations. The effects of the location of an applied rf electromagnetic field and of the injected particle size on the plasma jet characteristics and the particle behavior are clarified by numerical simulation. It is concluded that the particle dispersion is effectively influenced and, furthermore, the plasma temperature and the particle temperature can be strongly controlled by applying the rf electromagnetic field to the nozzle. The reasonable agreement of particle velocity between calculation and experiment is obtained.
