Elastic Water-Hammer Theory–Based Approach to Discharge Calculation in the Pressure-Time Method

Publication: Journal of Hydraulic Engineering
Volume 143, Issue 5

Abstract

An original numerical procedure based on the elastic water-hammer theory, with special solutions of continuity and momentum equations modeling the unsteady liquid flow in pipelines, has been developed for discharge calculation within the pressure-time method framework. The results of the discharge measurements carried out in two different hydroelectric power plant units using the pressure-time method with the newly developed procedure are compared with those obtained using the standard procedures. An analysis of the advantages of the proposed method is presented. Among others, broader universality of the proposed method and significantly lower sensitivity of calculation results to assumed integration limits are pointed out.
