Numerical study of the thermally conductive finite thickness walls impact on heat transfer regime in a closed system in conditions of radiant energy supply

Research output: Contribution to journalConference article

Abstract

Plane problem of thermogravitational convection in a closed rectangular cavity is numerically solved in conditions of radiant energy supply to the one of the boundaries. Differential heat transfer parameters (fields of temperatures and stream functions) for the conjugate (only vertical walls, only horizontal, vertical and horizontal walls) and the nonconjugate formulation are obtained. Temperature distributions in the Y direction in the cross section along the axis of symmetry showed that the presence of heat-conducting finite thickness walls leads to a redistribution of the energy which is accumulated by gas and enclosure structures.
