CAVITATION IN HORIZONTAL PIPELINES DUE TO WATER HAMMER

Some effects of water hammer in horizontal pipelines are investigated for the case where the pressure reaches vapor pressure. A theory based on the presence of nuclei is set up, but fails where the growth of the bubbles becomes unstable. Based on the conclusions of the first approach, a schematization is chosen in which the celerity or vapor pressure is reduced to zero, while for higher pressures the celerity is assumed to be the normal water hammer celerity. Some calculations are made for a model pipeline 200 m in length with uniform flow in which the flow is suddenly interrupted. The theory gives a good description of the general behavior of the process in the model. However, the theory does not predict the observed wave dispersion.
