Abstract

An experimental technique for investigating the air flow passing a domestic electric fan by using flow visualization and high speed photography is reported in this paper. A rotary-prism type high speed camera and a motion analyzer were applied in the experiments to investigate the flow pattern closely neighboring the fan blades. The smoke emerged from dry-ice was used as the trace particles. The particle paths and some significant flow phenomena in the flow field were then clearly observed. On the basis of the results obtained by use of this technique, significant improvement over the existing ceiling fan blades has been made for some dozen manufacturers in both mainland China and Hong Kong, resulting in great benefits.
