This suitability of the k-ω turbulence model was linked to the better near wall treatment by this model as compared to the k-e based models. The results for the fin pitch study indicated that the decrease in the fin pitch causes a decrease in both heat transfer and flow friction ...
There are three basic processes of heat transfer namely conduction, convection and radiation. In most problems of practical importance two or sometimes all of these modes may occur simultaneously. The authors discuss these processes, an understanding of which is vital for the thermal design of ...
