Influence of Thermal Boundary conditions on Natural Convection Heat Transfer in a Wavy Walled Square Cavity with Adiabatic Block

Abstract

The aim of the present study is to analyze heat transfer characteristics for natural convection flows in a square enclosure with wavy right wall filled with air(Pr=0.71) having uniform heating on bottom wall and adjacent cold walls with a adiabatic square block inside. This geometry and the following results can be used for analysis in heat management of building architecture, solar collection devices, having walls with surface roughness. The design/methodology/approach of these numerical solutions is the finite element analysis by a commercial software COMSOL Multiphysics version 5.6. The choice of consideration of sinusoidal heating gives a better analysis of heat transfer analysis in this square geometry with wavy wall and with adiabatic block inside has not been investigated by numerical or experimental basis before and therefore, it is this motivation that results in this numerical investigation.
