Scientific paper

The effect of viscous dissipation on mixed-convection flow about a rotating sphere with a prescribed uniform surface heat flux (UHF) has been investigated analytically. Merk's (1959) type of series expansions is used to obtain the heat-transfer rate and the skin-friction coefficients. The results are presented for Pr = 1; rotation parameter = 0 and 1; buoyancy parameter = 0, 0.5, and 1 and various values of the dissipation parameter at various angular positions. As in the case of uniform wall temperature (UWT), the heat-transfer rate decreases with viscous dissipation. It is also observed that for an equivalent viscous dissipation effect, heating by UHF yields larger Nusselt number than heating by UWT.
