Abstract
The characteristics of electrohydrodynamic (EHD) gas pumps have been experimentally evaluated. Two tubes of different size were used to house the EHD gas pumps. Experiments were conducted using positive direct current with voltage varying from 13 kV to 30 kV. The applied voltage at which flow was induced correlates well with the electrode spacing. Air flows with a uniform velocity profile were induced in the smaller tube and an inverted parabolic profile in the larger tube. The results also show that the ionic wind velocity increases to a maximum value and then decreases to an asymptotic value.
