We propose a flapping wing type micropump, which is categorized as a velocity pump. The kinematics of the flapping wing consists of heaving and pitching motions like insects. Two dimensional computational fluid dynamics for a flapping wing type micropump is conducted to assess the no load flow velocity as the performance of the pump and optimize the wing kinematics. The numerical results indicate that the flapping type micropump shows high flow rate when the wing motion has larger heaving amplitude. In this case, the flapping type micropump utilizes the interaction between the flapping wing and pipe wall to enhance flow velocity, which is similar to the “clap-and-fling” effect by a pair of flapping wings of an insect.
