Oval Tube Serpentine

The most common problem related to fluid mechanics application is the frictional (CD) drags due to the form of objects. This friction losses can be reduced by turning the form of the object, which is contacting with the fluid, into a more suitable shape. The shape of oval tubes is more appropriate for shape comparing with circular tubes. At laminar and turbulent flows, the frictional drags (CD) of circular tube and different types of oval tubes are described in the below table. For example, comparing a circular tube and an oval tube; R1:R2 rate is 2:1; the frictional drags of the oval tube is 1.5 times less then circular tube. Because of this reduction, although the air-side pressure drop decreased, also fan motor needs less energy.

Oval tubes can be used to produce both spiral finned serpentines and stamped-rectangular finned serpentines. Available dies about oval tubes are specified with stamprectangular finned serpentines. Spiral finned serpentines are produced like standard spot welded serpentines.
