N2 - Various approaches are considered in the method of smoothed particle hydrodynamics (SPH) for calculating the volume concentration of gas phase in a liquid during the rarefaction or destruction. A scheme for calculating the concentration of gas phase, consisting of three stages, is proposed. At low concentrations, the calculation is carried out according to the full model, which includes the laws to describing the concentration dynamics. At high concentration the simplified model is used, when the change in concentration is determined by the dynamics of liquid. When the maximum concentration is reached, corresponding to a single particle without neighbors, the rate of concentration growth is fixed and the further development of the process is governed by inertia.
