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