“…As seen from this figure, heat transfer coefficient increases with the increase in clearance gap between the fin tip and shroud and it approaches the results obtained for the fin arrays in the absence of a shroud (see e.g. Baskaya et al[7]). The increase of the clearance gap between the fin tip and shroud causes an increase in the magnitudes of velocity and consequently in the flow rate of air entering from the open ends of the fins into the channel.…”

“…It was found that for a given base minus ambient temperature difference, the convection heat transfer rate from fin arrays takes a maximum value as a function of fin spacing and fin height, and a correlation was also presented. Baskaya et al [7] carried out a numerical study of natural convection heat transfer from horizontal rectangular fin arrays. They utilized a CFD code to solve the three dimensional www.elsevier.com/locate/ichmt elliptic governing equations.…”

A new type of metal-plastic composite heat radiator with hemispherical microstructure array was proposed in this paper. The influence of the geometrical parameters of the microstructure array, including size of the hemisphere, configuration of hemisphere, tilt angle of the radiator, thermal conductivity and radiation emissivity of the plastic, on the process of heat transfer under natural convection were numerically simulated. It was concluded that the metal-plastic composite heat radiator with hemispherical microstructure array had comparable heat transfer behaviors with those of metal heat radiator. So it is possible to replace metal heat radiator by such a metal-plastic composite heat radiator in case of high moisture or corrosion applications. Under the same volume, the cooling capacity of the heat radiator made of metal-plastic was 20 times as the heat radiator made of metal. The heat flux of plastic plate with hemispherical microstructure was superior to the ordinary flat plastic plate. And the former heat flux was 2050 W/m 2 , about two times as the latter, 1272W/m 2 . The optimal inclination angle of the heat radiator with maximum heater flux was around 45°.

In this study, heat transfer, flow structure and produced entropy due to natural convection in a threedimensional cavity heated via heat sinks are investigated numerically. One wall of the cavity is heated via pinfins and opposite wall is maintend at lower temperature. Remaining bouandaries are considered as adiabatic. Finite volume method is used to solve governing equations. Three geometrical cases are tested according to number and location of the fins. Other governing parameters are Rayleigh number and fin length. Number and length of the fins were found to be the most effective parameters on both heat transfer and entropy generation.
