摘要：

A high-order asymptotic solution for heat transfer of a laminar flow with low Prandtl number is attempted. The previous two models - conventional and two-region model - result in over and under estimation of heat transfer rate respectively. Hence velocity field is chosen to lie between the two models to give better results, and an equation is developed. Comparison is carried out between the performance of three theories of different Prandtl numbers.
