Hello,

I am new to flow simulation and need advise on how to simulate water flowing through an intake model (see attachment) . Is it possible to simulate water coming through the top section and eventually coming out of the hole (pipe) in the rectangular chamber? How would I go about doing this? The purpose is to find the relevant velocities of the water passing through the model (made of concrete) and also the turbulence of various designs.

Any help would be great!

Kind regards,

Jonny

Hi Jonny,

If the water is interacting with the air, this may not be the best simulation to do with Flow. In Flow one of the first steps is to define something called a "computational domain" which is the volume occupied by the fluid (water). If you're pouring water into the top part, the computational domain isn't very well defined because you don't know where the water ends and the air begins. Unfortunately, flow can not mix two fluids of dissimilar state (gas and liquid interaction is not possible).

I suggest is either finding another way to do it (I think it could be solved with differential equations) or you could assume a computational domain.

All the best,

Nick
