Numerical Simulation of Two-Phase Flow Produced by a Nozzle Taking into Account the Early Crisis of Drag for Droplets and Interphase Mass Transfer
A numerical experiment on the simulation of the two-phase flow formed during spraying of a liquid in a gas by a nozzle has been described. The distinguishing feature of the mathematical model is that it employs the differential equations describing the nonstationary flow of a compressible fluid as the initial equations. To transit to their difference analog, the known Lax–Wendroff algorithm has been used. The same numerical model was used to calculate the interfacial mass transfer in spray flow. For this purpose the basis differential equations of the proposed model have been supplemented by the equation of impurity mass transfer from gas to droplets.
