Abstract: In order to understand the plasma jet-liquid media interaction characteristics, a high speed digital camera system was used to record the propagation process of plasma jet in liquid media in cylindrical chamber. The properties of the axial and radial displacements of plasma jet in liquid media and the change in its spread speed with time were obtained. Based on experiment, a two-dimensional-axisymmetric, unsteady mathematical model was developed. Numerical simulation of this process was carried out. The temporal and spatial distributions of volume fractions of plasma and liquid were obtained. The axial displacement calculated from the numerical simulation matches well with that from experiment. The distributions of pressure, velocity and temperature of the flow filed were obtained, and the discontinuous mechanism of Taylor cavity was analyzed.
