Sneak Preview

Take a quick look at Hytran's advanced graphical display of transient behaviour.

The simulation is of a rising main with a single pump delivering to a reservoir. The transient pressure which occurs at the pump station on pump trip is displayed. Note the following as you run the simulation:

  • Instantaneous pressure variation with time along the pipeline is plotted
  • Pressure variation with time at the pump location is shown in the insert chart (blue line)
  • Flow direction is indicated by the blue arrows (forward flow) and the red arrows (reverse flow)
  • Column separation is identified by black dots in the pipe at the upstream high point
