The motion of a incompressible fluid along a vibrating wall is analysed by Havelock, but it is concerned with the vibration parallel to the wall surface, and the case the vibration is normal to the surface gives a more interesting problem. But in the latter case, in relation with the wave motion the compressibility of fluid must be taken into account. In this paper, along a plane wall a viscous laminar flow of a compressible fluid with uniform velocity gradient is assumed, and the influence of lateral vibration of wall, especially to the frictional resistance is analysed. As a conclusion, the ratio of increase of resistance is propotional to the square of Mach Number of vibration velocity of wall.
