摘要：

The objective of this work was to improve the conventional asymptote for small Prandtl numbers by a simple two-region model to eliminate the physical inconsistency. An explicit equation for the local Nusselt number is obtained with very good accuracy for Prandtl numbers less than 0. 1, for all possible accelerating and decelerating flows. The solution converges rapidly to the exact solution as the Prandtl number decreases, and becomes exact at zero Prandtl number.
