A numerical algorithm is developed in the work for 2D convection problem with phase transitions in the stream function - vorticity -temperature formulation. Special approximations of convective terms are constructed via central differences. Numerical implementation of the operator-splitting scheme used in calculations is based on the solution of elliptic grid problems at every time-level. The algorithm validation is conducted on the benchmark solutions for buoyancy-driven flow with phase transitions in a square cavity with side walls of different temperatures at various Rayleigh number values.
