- •
Fin side heat transfer characteristics of a wavy finned flat tube heat exchanger are reported.
- •
Relation between heat transfer and the intensity of longitudinal vortices is inspected.
- •
Relation between heat transfer and the intensity of transversal vortices is inspected.
- •
Intensity of longitudinal or transversal vortices cannot uniquely determine Nu.
- •
The suggestions for improving the heat transfer performance of fin side are reported.
