Original Abstract

Drinking water in developed settlement is delivered by pipeline network, which is often very large and complex. The pressure in the pipeline system has to be kept in certain limits, which are given in standards. When the pipeline significantly changes the altitude, the pressure has to be reduced, mostly by a pressure reducing valve, which is able to keep constant downstream pressure regardless the upstream pressure for arbitrary flow rate. The pressure reducing valve works well under steady conditions, but it can have a negative influence when working conditions are changing and the system is looking for a new steady state. The paper is focused on numerical simulation of water delivery system with a pressure reducing valve. Model is based on one-dimensional description of unsteady flow and several unsteady scenarios are modelled. A special attention is paid to influence of pressure reducing valve on water hammer propagation.
