Abstract

An exact analytical formula for the averaged force acting on a two-dimensional oscillating body situated in a uniform flow is obtained on the basis of the incompressible Navier-Stokes equations and the general force formula obtained by Isao Imai in 1974. It is revealed that the averaged force is determined only by the asymptotic behaviour of the time-averaged flow if the flow is time-periodic. The formula is applied to study the animal's hovering flight.
