The effect of curvature on the slamming force in water impact of a WIG craft

摘要：

Prediction of hydrodynamic loads during water impact is of great significance in the struc- tural design of ying vehicles. No theoretical tool is available to handle this complicated phenomenon exactly, and the experimental procedures in the laboratory are both time-consuming and expensive. In this paper, numerical simulation of two phase ow in water impact problem of a WIG (Wing In Ground effect) is taken into account and the effect of changing the curvature of the step section of a WIG on the slamming force is investigated and the results are compared with a conventional wedge shape results. The governing equations for unsteady two phase ow including continuity and momentum are solved using a finite volume discretized method code.
