The time-dependent heat transfer process in the region of a turbulent separation bubble at the leading edge of an isothermal square leading edge plate is modelled numerically. A discrete-vortex model is used to determine the velocity field and a third-order upwind differencing technique is used to calculate the thermal field. The prediction of the mean Nusselt numbers is compared with experiment. The model predicts the instantaneous streamlines, isotherms and local Nusselt numbers at the plate surface. The influence of the large-scale vortex structures on the local heat transfer is determined.
