A statistical analysis of an ionic air moving device for the optimization of geometry.

摘要

Ionic air moving devices are similar to fans and blowers but move ionized air molecules between electrodes with a high electric field. Steady air flow is generated from the transfer of momentum when charged molecules collide with uncharged molecules. Ionic air moving devices are seen as less efficient as fans and blowers. The optimization of the device's geometry can increase its output efficiency. In optimizing the geometry of an ionic air moving device the literature suggests that varying the parameters of the number of ionization sites, the distance between the ionization sites and the collector, the height of the collector, and the voltage influences the air flow of the device [1-5]. In the current study, an analysis of the parameters though the use of design of experiments statistically showed which factors significantly influences the air flow. The ionic air moving devices parameters were statistically evaluated with the use of MinitabRTM. The distance between the electrodes, and the voltage were shown to be significant and to have the most effect on the ionic device in terms of air flow.
