Abstract
The discrete vapor cavity model, for describing pipeline transients involving vapor column separation, is based on the method of characteristics with specified time intervals. Vapor cavities are confined to computing sections and a constant acoustic wavespeed is assumed for the liquid. High pressure pulses, which exceed the initial pressure rise due to valve closure, can occur when a cavity collapses.
