2 ) a computational procedure is proposed to solve the interaction problem of elastic structure and fluid . little simplification of fluid is carried out . the coupling algorithm solves the equations for the fluid and solid domains independently of each other 2 )在计算流体动力学( cfd )的基础上,发展了一种流固耦合计算模式( fsi ) ,流体为粘性介质,采用ale格式处理流体和结构之间的移动界面,流体域和固体域分别独立计算,程序控制传递流体压力及固体位移和速度作为对方的边界条件,实现耦合计算。
