ESDU 69011:1969

ESDU 69011 provides Stanton number data for the forced convection heat transfer between a two-dimensional turbulent boundary layer and a smooth flat plate. Both local and mean values of Stanton number are given for a uniform wall temperature and zero pressure gradient in incompressible flow for Reynolds numbers based on distance from the virtual origin from 100000 to 1000 million and for ratios of wall temperature to recovery temperature from 0.25 to 2. The effect of Mach number over the range 0 to 5 is also covered. The data were obtained from a large number of wind-tunnel experimental data for local heat transfer which were analysed by means of a Reynolds analogy factor using the Spalding and Chi method for skin friction coefficient (ESDU 68020). The resulting Reynolds analogy factors are given as functions of Reynolds number in graphical form. Lower boundaries of Reynolds number for the applicability of the data are also given.
