Abstract
This paper presents the characteristics of micro induction EHD(Electro Hydro Dynamic) pump in which the fluid has a temperature gradient to the transverse direction of a traveling wave. The effects of the channel depth, the wave length and wave form of the treveling wave has been investigated in micro pump. The effect of temperature gradient also has been investigated. The fluid velocity becomes large as the wave length becomes small and the temperature gradient becomes high. The channel depth has little influence on the fluid velocity. The EHD pump driven by the square wave has the larger fluid velocity than that driven by the sinusoidal wave.
