Summary

The effect of three-dimensional hydrodynamics on the enhancement of steady, laminar heat transfer in corrugated channels is studied using a combination of analytical and numerical techniques. In the three-dimensional case the corrugations are sinusoidal in two orthogonal directions. A small mean flow in the transverse direction leads to an increase in the heat transfer by allowing particles to cross between the recirculation zones and the main flow. As the transverse flow becomes stronger, the recirculation is destroyed and there is a corresponding decrease in heat transfer.
