A Vibrating Elastic Plate Flow Generator (VEPFG) is an application of a vibrating plate to a flow generator. It became recently to be utilized for flow generation, in addition to propulsion purposes such as boat thrusters. The fluid-dynamic characteristics of the VEPFG as a fluid-machine, however, have not been fully elucidated. This paper aimed to make clear the pumping action, i.e. flow energy input, flow rate and induced flow field, in addition to the thrust. The performance parameters were made dimensionless by normalizing on the basis of the driving conditions at the leading-edge. The parameters thus defined were proposed in place of those of the thrusters. They could be useful for planning the VEPFG. The induced flow fields were analyzed on the assumptions of small-perturbation and potential flow. The results will serve as a referential base for comparing with actual VEPFG flows and experimental results.
