Modeling Vortechs
Modeling Vortechs
(OP)
Modeling an offline vortech unit with a bypass for the first time in hydrocad and need some advice on how to go about it. the bypass is provided at an upstream manhole; outlet above the inlet to the vortech to a down stream manhole. i have tried a number of different ways but dont see the results i was expecting altough it seems that it works





RE: Modeling Vortechs
Remember that a vortex valve is modeled in HydroCAD as a pond outlet device, so you need to think carefully about how you define the "pond" storage and your outlet controls. I assume your bypass would be a separate outlet device, such as a weir or orifice.
If you have questions about a specific model you may want to send the file to HydroCAD support. Also please see the paragraph on "offline storage" at www.hydrocad.net/pondstore.htm

It sounds like the "pond" will be the upstream manhole, which will have two outlet devices: The Vortech and an overflow device. The overflow could be modeled as a weir or orifice.

good luck
RE: Modeling Vortechs
the way the system is arragned is: manhole with 8" to the vortech and bypass to the downstream manhole with the 8" inlet coming back "online" at that manhole, which is the arrangment required by the NYSDEC for this device.

again the vortech should not be confused with the vortex, they are separate entities.
