Abstract

This paper describes the three-dimensional elliptic simulations on the mixed convection heat transfer in a horizontal square channel with high and low temperature side walls. Governing equations were solved for various Prandtl numbers and Re=100 by QUICK and SIMPLE method. Three dimensional spiral flows caused by buoyancy force could be found along the main flow direction for comparatively low Prandtl numbers. However, the streak lines were parallel for high Prandtl number. The effects of Prandtl numbers on the heat transfer were also discussed. 1 Introduction Very sophisticated manufacturing technologies and many micro- structures are utilized in the microelectron
