Abstract

The performance of axial fans in close proximity to EMC screens has been analyzed by means of an experimental parametric study. The following geometrical parameters have been studied: the hub-to-tip ratio, the ratio between fan thickness and fan diameter, the porosity and the thickness of the perforated plate and finally the distance of the perforated plate to the inlet and the outlet of the fan. The screen porosity has been found to be the most important parameter. The distance between the screen and the fan is significant to a certain extent if the screen is placed at the inlet of the fan, otherwise the distance is of no importance.
