Abstract

This work involves a numerical investigation on free convection heat transfer occurred by a hot cylinder immersed in a square duct cooled from one side under different temperatures. Simulations have been done for a large ranges of Rayleigh number (103Ra ≤107 ) and right wall temperature (0≤Tr ≤0.75). The results displayed that Nu is enhanced with rising in Ra and decreasing in Tr. The value of Nu is decreased with rising in Tr, where the maximum reduction in Nu is about 32% for Tr=0.75 as compared to Tr=0. The maximum enhancement range for Nu is found between 50% and 100% for low Ra and between 20% and 30 % for high Ra. The variations of local Nu display that Ra has an extremely actions on the characteristics of flow and temperature fields.
