基于SPH模型研究二维楔块入水水动力问题。提出了一种SPH方法的无反射边界处理来减小计算域的大小。使用两相SPH模型模拟进水和围水的细节。同时预测型腔和楔周围的水流以及型腔内的气流。比较施加在楔块上的流体动力以及腔体和射流的几何形状方面的实验数据，获得了良好的一致性。
The hydrodynamic problem of two-dimensional wedge entering water is studied based on SPH model. A non-reflection boundary treatment for SPH method is proposed to reduce the size of computational domain. The details of water entry and enclosing are simulated using two phase SPH model. Both the water flow around the cavity and wedge and air flow inside the cavity are predicted simultaneity. Good agreement is obtained comparing experimental data in terms of both the hydrodynamics force exerting on the wedge and geometry of the cavity and jet.
