| Abstract |
This study is to investigate the pressure wave characteristics and the absorption of maximum and minimum pressure generated by instantaneous valve closure at the end of the straightening copper piping system with and without a water hammer arrester. Experiments were conducted under the following conditions : initial pressure 1∼5 bar, flow velocity 0.6∼3.0 m/s, water temperature 20℃ and air volume of water hammer arrester 80∼180 cm3. Experimental results show that the optimum air volume of water hammer arrester is 110 cm3. |
