SIMULATION OF HEAT TRANSFER HARACTERISTICS FOR

Abstract

Heat transfer behavior for non-Newtonian power law fluids flow in circular duct with laminarflow, fully developed, constant heat flux. And constant wall temperature was studied. Amathematical model which is capable of accurately predicting temperature and velocity profiles andheat transfer rates for power law non-Newtonian fluids was obtained. The theoretical Nussultnumber was compared with previously published works where good agreement was noticed, whichcan be easily evaluated using theoretical model as a function of power law index only for constantheat flux and as a function of power law index and Graets number for constant wall temperature. Itwas found find that Nussult Number decreases when values of power index increases.
