- •
In the case of the cross-cut applied wavy fin, substantial heat transfer enhancement can be found.
- •
The optimum position for the cross-cut flow control was at the region right after the wave peak.
- •
The optimum length for the cross-cut flow control was 0.3Dh.
- •
The optimized cross-cut flow control can increase the performance of the wavy fin.
