A numerical algorithm is described in the work for 2D convection problem of fluid in porous medium in the stream function — vorticity — temperature formulation. 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 of fluid in a square cavity with side walls of different temperatures.
