Using the computational fluid dynamics software fluent 6.3 to research the heat transfer characteristics of a rectan- gular fluid channel which has the ordinary 3-D rib or the spiral warped surface 3-D rib, the heat transfer and resistance prop- erties is analyzed therein in the case of Reynolds number which from 2000 to 10000 and angle of attack/3 is 45°. The results show that the average nusselt number Nu and the skin friction coefficient for spiral warped surface 3-D rib are both larger than the ordinary ones. At the same time, using the co...
