Two-phase open channel flow
I could do with some help on this. I'm trying to model flow in an open surface pond. How do I create a gambit model that allows for two-phase flow? The tutorials don't help as they apply an axis of symmetry, which this pond doesn't have. Further, once i get it done, how do i run this model with Fluent? What parameters particularly do i need to look out for? What equation models are recommended if im trying to study the effects of bluff bodies in the flow? I'm experimenting with the k-epsilon equations currently. Thanks guys.

Re: Two-phase open channel flow
try adapt/region/(define regions of phases) go to: initialize/patch (choose adapted region, let say you`ve adapted bottom part of channel so write one for this part of your chanel)
wich model to use ?? It depend if your flow is laminar or turbulent |
Re: Two-phase open channel flow
Thank you very much for your reply. However i'm still not sure how to generate a region to specify the phases. Since i'm modelling a 3-D volume, how do you suggest i define the regions in Gambit before going to the Fluent??Do i create another volume or shall i just seperate the 2 regions with different phases by using a surface??
Thank you. |
Re: Two-phase open channel flow
In Gambit you can just seperate your volume and define them as different zones!!! Gambit Zones Command Button - Specify Continuum Command Button! You can name your zones on your own here! During exporting them to fluent, fluent it self names the different zones again with interior! I do not know why, but there is no problem with it!!
