In this paper, the outflow of liquid in the coflowing airstream from a shock-jet nozzle is examined using a commercial software package with varying initial and boundary conditions. Gas-dynamic characteristics and distribution fields for pressure, velocity, temperature and volume fraction of the two-phase flow are obtained. The influence of thermophysical properties of the liquid on the process of jet dispersion is determined. The results of simulation of the liquid outflow from the shock-jet nozzle at constant and real (temperature dependent) thermophysical properties of the liquid phase are compared. The qualitative and quantitative influence of the input pressure in the nozzle on the jet dispersion process is determined. As a result of a series of calculations, the minimum required characteristics of temporal and spatial resolution for the correct solution of the problem are identified. It is established that the volume content of the liquid phase is higher with real thermophysical properties compared to the constant ones.
