Abstract

In this paper, flow of a power law fluid past a stationary spheroid is numerically investigated. The ranges of parameters investigated in this study are: 10 ?Re ?100; 1 ?Pr ?100; 0.4 ?n ?1.6; and 0.5 ?E ?2. The variation of local Nusselt number on the surface of both oblate and prolate spheroids was obtained. The effect of modified Reynolds number, modified Prandtl number, axis ratio, power law index on average Nusselt number were also obtained. A correlation was developed using least squares regression analysis. The Nusselt numbers predicted using this correlation were found to be in good agreement with the data of earlier investigators.
