摘要：
The momentum and energy equations describing the steady cross-flow of power-law fluids past a rotating heated cylinder have been solved numerically. The results highlight the influence of dimensionless rotational velocity (0 <=alpha <= 6), power-law index (0.5 <= n <= 1.5), Prandtl number (1 <= Pr <= 100) on the drag and lift coefficients for Reynolds number of Re = 40, surface-averaged values of the Nusselt number, detailed flow and temperature fields.
