- Modèle d’une conduit simple: station de pompage au debit, réservoir anti-bélier 1.5km et soupapes 3.7km & 9.5km.
- Haut de l’écran à gauche: graphique dynamique temps en abscisse.
- Haut de l’écran à droite: schéma modèle.
- Bas de l’écran: graphique dynamique cours de canalistion en abscisse.
- Simulation panne de courant: réservoir anti bélier est trop petit, les soupapes ouvrent. Apres 1 minutes 20 secondes la soupape [3.7km] ferme et causer ondes pression.
- Model of single pipeline: Pumping station at the start of the line with a Surge Vessel 1.5km and Air Valves at 3.7km & 9.5km.
- Top left of screen: Time based graph flow from Pumping Station & water level in Surge Vessel
- Top right of screen: Model Schematic components change colour during simulation
- Bottom of screen: Long profile of pipeline illustrates the head during the simulation together with the maximum & minimum heads for the simulation.
- Simulation of Power Failure at the Pumping Station: Surge Vessel provides some attenuation of pressure but it is too small and so the air valves open. 1 minute 20 seconds after power failure closure of the Air Valve at 3.7km leads to further pressure surges.
