| Abstract: | The rational arrangement of air valve in pipeline directly affects the safety of long-distance water-supply project for protection of water hammer.Based on the analysis on water hammer and to comply with the design standard of maximum allowable negative pressure in the process of operation,the general framework of theoretical analysis and numerical simulation on optimization of air valve are established in which the number of valve,locations and spacing intervals are explicated,and the principle of air valv... |
