    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…

    Hello I have modeled a raw water pumping line from a low to a high elevation using Hammer to compute up surge and down surge. My problem is even when using a hydronumatic tank i am getting negative pressures in the pressure envelope at the tail…

    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…

    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

    Matt Baird
    Matt Baird
    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…

    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…
