摘要
将求解船舶兴波问题的Rankine源数值计算方法推广应用到水面边界条件为碎冰面、纯冰面和半冰面-半水面等气垫船破冰中不同类型的兴波问题.对不同类型兴波问题采用统一形式的基本方程,通过面元法与有限差分法相结合的方法对方程进行数值离散.重点对气垫船在全冰面、半冰面-半水面上运动时的兴波进行了数值计算,兴波阻力和波形等计算结果与相关文献符合较好.
Water waves of different type in broken ice by ACV （air-cursion vechice） were computed numerically by a genetic governing equations. The Rankine source panel method which was originally used in marine hydrodynamics was extended to water wave problems in broken ice by ACV with broken ice, infinite or semi-infinite ice sheet on water surface. Wave patterns and wave drags were computed for total ice and semi infinite ice problems. Computed results are in good agreement with the a vailable theoretical ones.
