The article presents the result of the numerical simulation of the turbulent flow for a rib-step system by the RANS method at the Reynolds number, calculated by the step height and average flow rate velocity, Re = 5000. The data obtained in these studies showed the influence of divergence ratio on heat transfer in a flat channel with a transverse rib acting as a vortex generator. It is shown that with an increase in the divergence ratio, the length of the recirculation zone increases, while the position of the heat transfer maximum varies slightly.
