• Modeling one way surge tank in a existing pumping station

    I have modeled a surge tank like one way ussing choosing "false" for "treat as junction?" and "true" for "has check valve" in an existing pumping station and computing a transient simulation (pump shut down after 5 seconds), but, when i check the the…
  • Modelling a Pelton

    I am modelling a hydro station with 4 pelton units for pressure rise and mass surge. I have currently modelled these as a discharge to atmosphere element as is recommended in the Hammer knowledge base. However, using a discharge-to-atmosphere element…
  • Cla-Val Control Valves in Water Hammer

    Has anyone simulated a Cla-Val surge anticipator (Model 52-03) or surge relief valve (Model 50-01) in Water Hammer? The surge anticipator valve seems straight forward, but I'm not sure what kind of variables to use for time to open, time stays open, or…
  • Hammer Pump Transient Properties

    Is there anyway to make a responsible assumption for the pump transient properties if accurate data is not available? I have a distribution system model that I've been asked to do some transient analysis for. The model has detailed pump curves but I don…
  • Hammer Analysis in Raw Water Transmission System

    I'm trying to evaluate the need for surge protection at new well locations in a raw water transmission system. I have a network of 6 wells all pumping to the water treatment plant. I'm new to Water Hammer and surge analysis so I'm just looking for some…
  • Hammer: Pelton free-surface tailrace surge

    Hi I am currently modelling a number of pelton hydro station layouts. One option may (to be confirmed) include a tailrace tunnel with a free surface. Because the tail race tunnel is so long, surges upon start-up are a concern as could flood the pelton…
  • General Transient Modeling Help

    Does anyone have a good resource for learning and understanding real world transient problems and models? I'm fairly new to transient analyses but I have been through the Bentley training course. I have a couple transient models that I am currently working…
