4321 Effect of Hole Shape on Flow Resistance of Perforated in Natural Air Convection Flows
Details
This paper describes the effect of shape parameters on the flow resistance of perforated plates used in electronic equipment. In order to demonstrate the influence of hole shape on the flow resistance of perforated plates, measurement of 16 perforated plates and analysis of the results were conducted using the Design of Experiments (DoE) method. In the range of levels of DoE analysis assumed for electronic equipment, it was found that hole shape has little effect on flow resistance.
