Abstract

As shown by the examples given in this paper, a commonly used, commercially available water distribution network modeling software may produce unrealistic results for flow control valves (FCVs) with a nonzero loss coefficient. This paper presents and discusses a simple technique to remedy this problem. According to this technique, an FCV with a nonzero loss coefficient K is modeled as a composite link that consists of an FCV of the same setting with a zero loss coefficient and an artificial pipe of negligibly small major loss with a diameter equal to the FCV diameter and a minor loss coefficient equal to K. The proposed technique can be implemented using the discussed software without any modification of its hydraulic solver.
