一、问题的描述在波浪槽(如图一所示)中的无粘不可压缩流体的二维无旋运动在给定的座标系中可由标量速度势函数φ(x,y,t)给出
I. Description of the Problem The two-dimensional non-rotating motion of the non-viscous incompressible fluid in a wave tank (as shown in Figure 1) can be given by the scalar velocity potential function φ (x, y, t) in a given coordinate system Out
