Abstract
THE HYDROBLOW PHENOMENON occurs when there is a sudden change in the flow rate of transported fluids. A shock wave, which is formed at the place where the flow changes, travels along the pipeline, interacting with equipment and dying down according to a specific law. It is rather labour-intensive, and takes a considerable amount of time, numerically to analyse the wave processes in order to draw up maximum-pressure diagrams. A substantial quantity of information obtained from numerical calculation using difference schemes is as yet unused. The aim of the present study is to find an analytical approach for constructing a maximum-pressure-envelope curve.
