Laminar boundary layer on a flat plate at low prandtl number

Abstract

Using the method of matched asymptotic expansions, we obtain the first four terms in the low Prandtl number expansion for the recovery temperature and heat transfer in the flat plate compressible boundary layer (assuming a viscosity proportional to temperature). It is found that, provided the series are properly Eulerized, the results so obtained are good even when Prandtl number approaches infinity.
