Multiple Parallel Serpentine Channels with Square Bends

3 Multiple Parallel Serpentine Channels with Square Bends 

---

Since the serpentine channel with square bends provides a more effective contact area, multiple parallel serpentine channels are considered with square bends in order to take advantage of increased contact area as well as decreased pressure drop because of the parallel nature of the flow as shown in Figure 10.12d.
