This paper presents a calculation method for the 3-D unsteady cavitating hydrofoil problem. The method is based on a simple surface panel method “SQCM” which satisfies easily the Kutta condition even in the unsteady problem. This method is applied to the Wagner problem, heaving hydrofoil and the hydrofoil in sinusoidal gust. We show some calculated results for partially cavitating and supercavi...

A thin rigid plate is submerged beneath the free surface of deep water. The plate performs small-amplitude oscillations. The problem of calculating the radiated waves can be reduced to solving a hypersingular boundary integral equation. In the special case of a horizontal circular plate, this equation can be reduced further to onedimensional Fredholm integral equations of the second kind. If th...

Flying insects may enhance their flight force production by contralateral wing interaction during dorsal stroke reversal ('clap-and-fling'). In this study, we explored the forces and moments due to clap-and-fling at various wing tip trajectories, employing a dynamically scaled electromechanical flapping device. The 17 tested bio-inspired kinematic patterns were identical in stroke amplitude, st...
