The influence of different factors on the shape of pressure pulse at the liquid-vapor contact

The process of formation and propagation of the depression wave at spontaneous contact of cold liquid and saturated vapor is investigated in a gas dynamics approach. Modeling of wave processes was performed using Godunov’s method based on solving the Riemann problem on arbitrary discontinuity decomposition. The influence of various factors, namely, the kinetics of condensation and intensification of heat-transfer processes, on the pressure pulse form is investigated. Results of the investigation are in good agreement with results of modeling based on numerical solving the Boltzmann kinetic equation.
