Original Abstract

The solution of liquid flow with the moving boundary has many technical applications - for example the flow in the diaphragm pump, in the plunger pump, in the human heart and many other examples of unsteady movement of the elastic or stiff body in a liquid. The liquid flow induced by the unsteady movement of the boundary is presented in the paper. The flow description comes out from the Euler field conception, so the velocity vector and the pressure depend both on the spatial Cartesian coordinate and on time. The problem becomes more difficult, when time dependent movement of boundaries is assumed. The shape is generally changed in time and the coordinates xi that describe the boundary shape are function of time as well.
