Abstract

Numerical results are presented for the modelling of the spread of heat as a passive scalar contaminant on the basis of a second-order closure model in the mixing layer with an asymmetric mean-temperature profile superimposed on it. Present calculations are in reasonable agreement with experimental data on the region of countergradient transport for heat where the direction of heat diffusion is opposite to the mean gradient diffusion and where the production of temperature fluctuation intensity is negative.
