Default simulation problem

Posts: n/a
Hello all,

I am quite new to CFD and recently acquired the FLUENT/GAMBIT software for a Senior Mechanical Engineering Design project. I am having some trouble modeling some cooling tower piping and any assistance would be greatly appreciated. Here is the problem statement:

Water rises through an 8ft diameter pipe approximately 20 feet high and exits horizontally through two "flumes". Here is the complicated part, the water level reaches about four feet above the "flumes" and is open to the atmosphere. I am having trouble defining the boundary type for this part of the model. If my description is not enough explanation of the problem I am more than happy to e-mail you CAD drawings of the situtation. Thanks everyone for all of your help!

It seem that you have two fluid, water and air. In that case you need a multiphase model like VOF (Volume Of Fluid).
