| Abstract: | Arrangement of one-way surge tank that is an effective measure for water hammer control is crucial to the safety of long-distance water-supply project.This paper establishes a general framework of theoretical analysis and numerical optimization for the tank arrangement by using water hammer analysis with a criterion of avoiding negative pressure during operation.A general rule of arrangement on long-distance water-supply pipeline under different conditions is proposed,and the relationship between tank locat... |
