Abstract

The current study aims to numerically investigate free convection airflow within a horizontal cylinder with a linearly heated side wall. The computation of heat transfer and fluid flow structure has been carried out using the finite element software COMSOL Multiphysics. The influence of the heat source position on fluid flow and heat transfer is inspected. Special attention is paid to the effect of Rayleigh number and the heater position on energy efficiency within the cavity. The results indicate that the best heat transfer performance is achieved for low Rayleigh numbers and when the active wall is centered in the vicinity of 90°.
