TY - JOUR ID - TI - SIMULATION OF HEAT TRANSFER HARACTERISTICS FOR AU - Hisham .M.Al.Tamimi PY - 2009 VL - 2 IS - 3 SP - 654 EP - 663 JO - Al-Qadisiyah Journal for Engineering Sciences مجلة القادسية للعلوم الهندسية SN - 19984456 24117773 AB - 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.
