Hytran is an easy to use, but powerful simulator of water hammer in pipe systems including pipe networks.
Hytran’s graphical presentation of the phenomenon - in real-time along the pipeline as the pressure waves progress and reflect, and at user-selected fixed locations - imparts an almost intuitive understanding of the system performance.
The screen image mosaic left shows a simple pipe flow system consisting of a single pump discharging via 2,250m of 400mm steel pipe to a reservoir at an elevation 40m above the pump. The pipeline image and the steady-state pump performance curves are from our FluidFlow software; the transient pressure pressures at the pump generated by Hytran result from pump trip and column separation at the first high point.
The maximum transient pressure at the pump is approximately three times the pump duty pressure.
