Abstract [en]

Numerical simulations of an air-water transient flow in a pipeline, subjected to an instantaneous valve opening, are performed. Two cases are considered: a dead end and a venting system at the downstream part. An Euler-Euler model and a VOF model are used for analyzing the compressible multiphase flow. Results show that a small amount of entrapped air remains at the upper part of the pipe, influencing the maximum pressure. As the reverse flow occurs, air is absorbed back in the pipe through the orifice
