Abstract:
The expansion characterist ics and ex pansion processes of arc plasma jet in liquid are studied by means of fast-f raming camera system. From the analysis of the fast-framing pictures, the influence of discharging power and nozzle st ructure on the st ructural characters of plasma jet and the ax ial and radial expansion velocit ies of T aylor cav ity are discussed. The f ront expansion velocities of Taylor cavity measured in this paper are in good agreement w ith the result s of the former’ s, but several new discoveries about the structure of plasma jet are presented in this paper. There is a dist inct dark area betw een tw o-phase f luids, and the Taylor Cavity shows discont inuity in the expansion process.
