Numerical investigation of natural convection in a vertical slot with two heat source elements

Abstract Numerical modeling of natural convection air cooling of two heat-generating devices in an upright open-top slot has been considered. The heat sources are located on a vertical substrate of finite thermal conductivity, and the effect of different substrate material on the heat transfer performance has been quantified. The influence of the heat generation rate and the separation distance between the sources has been investigated. It has been shown that wall conduction is important, and for substrates with a finite thermal conductivity, it is essential that the conjugate analysis is employed.
