Heat transfer of a laminar flow passing a wedge at small Prandtl number - A new approach

A two-region model is presented which gives satisfactory results for the generalized heat transfer problem of a laminar flow passing a wedge at small Prandtl number. 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.
