摘　　要：建立了任意拉格朗日-欧拉(ALE)描述下的流体控制方程,可更方便计算边界运动流体问题和具有真实物理界面位移的流固耦合问题,应用基于动量、能量守恒的一致插值法可确保系统的动量和能量守恒。算例结果表明,该方法合理有效,可为有关科学研究和工程设计提供理论依据。The governing equation based on ALE description was more convenient for description of fluid-solid interaction with moving boundary and displacement of real physical interfaces. Consistent interpolation schemes based on momentum and energy conservation made sure that whole system can cater conservation of momentum and energy. According to the computing result, the method was reasonable and effective for scientific research and can provide theoretical basis for engineering design.
