32-55 SIMULAREA NUMERICĂ A UNEI VANE DE ECLUZĂ DE LA HIDROCENTRALA PORȚILE DE FIER I
NUMERICAL ANALYSIS OF A LOCK VALVE
OF IRON GATE I HYDRO
One of the valves of the intermediate head of the lock of Iron Gate I Hydroelectric Power Station was damaged; it was replaced by another version. In order to elucidate the cause of the damage was done a numerical simulation using ANSYS Fluent software. The simulation has required the modeling of parts of channel for filling/emptying of the lock, taking also into account the hydrostatic water pressure, not just those static or dynamic. The paper presents a modeling of steady flow through the valve which is in a certain position, which shows velocity and pressure fields and the forces on the faces of the valve.
