Abstract Nowadays, the cooling of heat elements is a challenge in electronics and thermal engineering. Such elements are widely used in rotating electronic systems. The present study deals with the effects of uniform rotation and the porous layer (as a control parameter) on free convection in an electronic cabinet having a local heat source. Horizontal walls of the considered cavity are thermally insulated, vertical walls are cooled and an isothermal heater with a constant temperature is in the middle region of the bottom border. Impacts of Rayleigh, Taylor, and Darcy numbers, as well as porous layer thickness on hydro- and thermodynamics have been studied. It has been revealed that a growth of the Taylor number suppresses the mass, momentum and heat transport, while an increase in the porous layer thickness results in the heat transfer rate diminution.
