Single Serpentine Channel with Square Bends

4 Single Serpentine Channel with Square Bends 

Serpentine channel designs with square bends. 

Contour plots for single serpentine channel with square bends, (a) Static pressure, (b) Dynamic pressure, (c) Total pressure, (d) Velocity magnitude. 

The square bends not only provide more contact but also exhibited consistently lower pressure drops compared to curvilinear bends.

Different flow channel design configurations, (a) Straight parallel channels, (b) Single serpentine curvilinear bends, (c) Single serpentine channel with square bends, (d) Dual 2-mm serpentine parallel channels, (e) Dual 1.2-mm serpentine parallel channels, (f) Dual 1-mm serpentine parallel channels, (g) Four 0.5-mm serpentine parallel channels. 

For a single serpentine channel, the effective contact surface area of the gas channels can be increased by replacing circular bends with square bends. A schematic view of the single serpentine channel with square bends is shown in Figure 10.21. The operating conditions are the same as those of the serpentine channels with curvilinear bends.
