Total heat transf. rate vs Total surface heat flux -- CFD Online Discussion Forums

August 22, 2005, 10:34	Total heat transf. rate vs Total surface heat flux	#1
Renato Sousa Guest Posts: n/a	I'm trying to simulate heat transfer through a wall to compare with known correlations. When I compute the heat flux with the surface integrals (Report-surface integrals - total surface heat flux), it gives a value that is in accordance with the outside and inside wall temperatures, being that flux equal to the conduction heat flux. However, using the Report-Fluxes - Total heat transfer rate - it gives a value higher than that. Does anyone know why? I'm not using any radiation model. Thank you.
