Abstract
In this present work, the local heat transfer and Nusselt number of developed turbulent flow in a convergent/divergent square duct have been investigated computationally. The angle of convergence of the duct is about 1°. The computational analysis had been conducted within the range of Reynolds number from 10,000 to 77,000. The outcome of local heat transfer coefficient and Nusselt number of computational fluid dynamic analysis of the convergent/divergent duct is compared with the experimental data. There is no significant difference in Nusselt number value of CFD and experimental analysis, but the heat transfer coefficient for CFD is slightly (15 %) higher that the experimental work due to heat transfer losses and practical difficulties in fabrication work.
