Investigation, Analysis and Computer Simulation of Transient

 and Steady Flow Conditions in Internal Fluid Flow Systems

Pumping Mains

Home Up

 

 

 

Maximum and minimum piezometric pressure head envelopes for a pumping main (main pumps at Ch 4462m; booster pump at CH26503m) created during the transient flow generated by the simultaneous trip of both pumps. Air Valve located at CH29000m.

 

 

 

 

Capabilities

The computer program (PTRAN) developed by Dr. Adrian Boldy, Director of HydroSim Consultants Limited, is capable of simulating the transient response of any conceivable pumping main equipped with any number of main and/or booster pumping stations.

In addition to the pump(s) any of the following boundary conditions may be incorporated into a given simulation:

        Pump flywheel
        Pressure relief valve
Bypass valve
        Pump discharge check valve
        Control valve
        Variable area surge chamber
        Variable area air vessel
        Feed tank
        Air inlet/outlet pressure surge alleviation valve
        Reservoir
