Summary

Wavy channels are especially used for the enhancement of heat and mass transfer in heat exchangers, regenerators, catalyzers and membrane moduls. In the concave part of the ducts a flow instability can be observed leading to longitudinal vortices comparable to the Goertlervortices at concave walls or the Dean-vortices in tube flows. The concave-convex walls in sinusoidal wavy channels alternatively enhances and destructs the longitudinal vortices resulting in highly complex flow and transport phenomena.
