Abstract |
The active heat transfer enhancement techniques have not found commercial interest because of the capital and operating cost of the enhancement devices. The majority of passive techniques employ special surface geometry or fluid additives for enhancement i.e. no direct application of external power. Whenever it is difficult to increase the rate of heat transfer either by increasing heat transfer coefficient or by increasing the temperature difference between the surfaces and surrounding fluid, the fins are commonly used. A perforation in the plate or fins is the one way that used to improve its effectiveness. Studies have introduced shape modifications by cutting some materials from fins to make cavities, holes, slot, grooves or the channels through the fin body to increase heat transfer areas and or the heat transfer coefficient. This work concentrates on experimental investigation of Natural convection heat transfer from perforated heated vertical plate with varying diameter circular perforations. The results of perforated plates are compared with heat transfer from the plain vertical heated plate. |
