摘要：
In this paper a new method for the determination of unsteady pressure with a tubing system is shown. The conventional methods try either to optimize the frequency behaviour of the tubing system by implementing restrictors or instantaneous jumps in the cross-sectional area or to correct the measurement by using the transfer function of the tubing system. The new method presented here simply uses a tube with constant, circular cross-section and solves the governing fluid-mechanic equations in the time-domain by numerically propagating in the direction of the spatial axis.
