ANALYSIS OF LIQUID SLUG MOTION IN A VOIDED LINE
摘要
A quasi two-dimensional two-phase flow cylinder model of slug motion in avoided 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 theoryof transfer momentum to estimate the pressure-time history of slug at the elbow,the result ofcalculation is not good in agreement with that of experiment.Analysis of the experiment resultsand the estimations of using the theory of transient two-phase flow indicate that an evident wa-terhamrner-response occurs in the slug,when the high-speed slug impacts on the elbow,and thepeaks and waveform of pressure-time history are dependent mainly on the propagation of tran-sient two-phase flow in the slug.
