Abstract
In this paper steady state forced convective heat transfer from a stationary unconfined spheroid to an incompressible power law fluid is studied numerically. The spheroid is assumed to be maintained at a constant wall temperature. The effect of Reynolds number (Re), Prandtl number (Pr), aspect ratio (E) and power law index (n) on the average Nusselt number was studied. The range of parameters investigated in this study is: 5⩽Re⩽100; 5⩽Pr⩽100; 0.5⩽n⩽1.5; and 0.5⩽E⩽1.5. The variation of local Nusselt number on the surface of both oblate and prolate spheroids was obtained. Further the Nusselt numbers for spheres lies between the prolate and oblate spheroids for all power law indices. A correlation was developed using least squares regression analysis.
