In this study, in order to develop the conventional fan using for gas transportation, thermal management and so on, electrohydrodynamic gas pump (EHD) driven gas by plasma has been proposed as next generation gas pump or fan. The EHD gas pump has no moving components, and so has some potentials for simple design, low noise, low vibration, longer life, higher energy efficiency and faster control of gas flow. In this time, the experimental investigations were conducted for the effects of size of the flow channel and electrodes, and their arrangement on gas velocity, flow rate, pressure distribution and pump efficiency. In addition, in order to develop pump performance, multi-stage type EHD gas pump were tested, too. The tendencies of pump performance for many design parameters of the EHD gas pump were revealed with the experimental results.
