Experiment and Numerical Study on Interaction of Gas Jet and Liquid Media
The object of this paper is to explore controlling methods on the combustion process in bulk-loaded liquid propellant gun. For that purpose, we designed a 4-stepped plane observing chamber, and conducted experiments of energetic gas jet propagating in liquid media by using high speed digital camera. The results show that the dimension of stepped chamber, gas jet pressure, nozzle diameter and liquid viscosity can affect the configuration of Taylor cavity and the turbulent mixing rate between gas and liquid dramatically. Based on the experiments, numerical simulations of the interaction of nonsteady gas jet with liquid media were carried out. The change characteristic of pressure, temperature and density in gas jet flow field has been obtained. The simulation results match well with the experimental results.
