| Sumario: | [EN] Water filling processes in pipes generate overpressures that must be considered so that the facilities do not fail during their operation. The filling manoeuvres with air trapped in water pipes have been studied by different authors. However, these investigations do not consider the behaviour of the air valves, which act as surge protection devices reducing the overpressures caused. This paper presents the mathematical model developed to simulate the hydraulic and thermodynamic variables that affect the process of filling water with air valves in simple pipes. A water pipe facility with a length of 7.3 m, a nominal diameter of 63 mm and an air valve installed at the highest point has been used to collect data for the validation of the mathematical model. |
