Abstract

This paper reports the results of numerical simulation of a steady-state convective flow of incompressible fluid in the gap between two coaxial cylinders. We assume that only one side of the inner triangular cylinder is heated, and the external circular cylinder is kept at constant temperature. It has been established that the rotation of the heater through a certain angle causes the convective plume axis to deviate. This strongly affects the flow pattern and the related heat transfer process. The maximum integral heat flux is observed when the heater is in its side position, and the minimum heat flux is observed when the heater is in the bottom position. Approximating the results, we obtain the dependence of the Nusselt number on the Rayleigh parameter and the rotation angle.
