The unsteady behavior of the flow driven by a jet suddenly injected into a cell is numerically studied by solving the axisymmetric two-dimensional compressible Navier-Stokes equations. This system of the calculation is a model of the laser ablation of a certain duration followed by a discharging process through the exit hole at the downstream end of the cell. The parameters for the calculation are the height at the middle position and the exit diameter of the cell. The influence of the shape and the exit diameter of the cell on the velocity at the exit hole and the exit downstream investigated. As the result, it was found that the wave form of the velocity variations at the cell exit downstream is roughly determined by the height of the cell.
