摘要：

Forced convection heat transfer across a 2D circular cylinder rotating at constant speed is investigated. Numerical simulations are carried out at constant values of Reynolds number in the range of 80-160. The non-dimensional rotation rate, alpha, is examined up to a maximum value of 5.3 for Prandtl number (Pr) 7. At constant Reynolds number, heat transfer suppression kicks off even at lower rotation rates contrary to the systems with lower values of Pr. Moreover, the heat transfer suppression parameter in such cases saturates at almost the double value at intermediate rotation rates as compared to the systems with low Pr.
