抄録

A theoretical solution of a pulsatile flow in the entrance region of a porous pipe was derived by Oseen's approximation reported in the previous paper when the radial wall velocity was constant along the pipe axis. According to Hornbeck's investigation, radial wall velocity alters due to the difference between the inner and outer pressure of a porous pipe. In the present paper, we dealt with a pulsatile flow whose radial wall velocity varies exponentially along the pipe axis. Dynamic characteristics such as velocity, and pressure coefficient are precisely discussed on the boundary conditions for pulsatile injection and suction from the pipe wall.
