• Behavior of pump in the case of Valve closure is not clear

    I am modelling a system, and one of the scenarios is an emergency shutdown of the flow control valve (FCV) downstream of the pump as shown in the following image: the FCV is modelled as a throttle control valve (TCV) with the properties of the original…
  • Re: Modeling a 1.5 second valve closure at Airplane Fueling Nozzle?

    Hello, The pumps are going to operate based on the system conditions (where the pump curve intersects the system head curve.) So, you'll need to "model what you've got" to get the right pump operating point. Meaning, if there aren't FCVs in reality…
