How to Reduce Pressure Surge in Dry Deluge Network
Two new features have been introduced into the PIPENET Transient module:
- You can now set the initial state of a pipe as being “wet” (full of fluid) or “dry” (containing no fluid). The default is “wet”. However an alternative setting of “dry” can be specified, to model pipes which are initially dry but which fill up with fluid during the course of the simulation.
- PIPENET Transient now allows the direct modelling of nozzle components within the network. The Spray and Standard sub-options of Transient both offer this capability, with the specification methods differing in detail.
Taken together, these new facilities significantly increase the range and accuracy of the network scenarios that PIPENET Transient can analyse, as we shall see in the example below. They have been implemented in response to an increasing need from our customers, and are key to accurately predicting the priming time of deluge systems.
