A fluid pump comprising a flow channel containing an fluid inlet and a fluid outlet and bounded by two side walls,a substantially planar flap positioned inside the flow channel, and an actuator capable of transmitting an oscillating force or torque to the flap,where the side walls extend from the inlet to the outlet and are substantially planar and parallel to the flap and extend beyond the downstream end of the flap towards the outlet by a distance such that l d ≥ l f /2, where l f is the length of the flap, where the side wall separation, h, length, l w , and width, w w, satisfy the relationships: l w > h and w w > h, whereby in use, the actuator drives oscillatory motion of the flap in a direction substantially perpendicular to the side walls with motion of the flap having larger amplitude near the outlet than near the inlet. |
