主　　题：Pipe flow Water hammer 

摘      要：A quasi two-dimensional two-phase flow cylinder model of slug motion in a voided line developed in this paper can predict reasonably the change of flow pattern of the slug, air entrainment, holdup and the distribution of axial velocity. However, if using the theory of transfer momentum to estimate the pressure-time history of slug at the elbow, the result of calculation is not good in agreement with that of experiment. Analysis of the experiment results and the estimations of using the theory of transient two-phase flow indicate that an evident water hammer response occurs in the slug, when the high-speed slug impacts on the elbow, and the peaks and waveform of pressure-time history are dependent mainly on the propagation of transient two-phase flow in the slug.
