Software has been developed for the numerical solution of hydrodynamics and heat transfer problems using GPU for simulations. The developed software has been used to study the conditions of natural convection in rotating spherical layers depending on the Ekman, Rayleigh, and Prandtl numbers, as well as on the initial distribution of temperatures. A family of quasi-stationary solutions differing in their flow structure has been obtained. There have been found the critical values of Ekman number with which the convection process breaks off.

Keywords: natural convection, computational fluid dynamics, spherical layer, GPU, OpenCL.
