Abstract
An experimental measurement of the effect of Taylor-Goertler vortex formation on the heat transfer through the boundary layer on a concave wall has been made. A theoretical analysis based on independent mean and oscillatory flow components indicates that, although the heat transfer rate will fluctuate periodically in the spanwise direction, there should be no overall increase in heat transfer. The experimental results indicate that there is a significant increase in Nusselt number in the presence of the vortices. Interaction between the oscillatory and mean components must be accounted for, if the theoretical model is to reliable.
