Hello users,
I´m relative new in the CFD topic, nevertheless I got the job to investigate the flushing of toilets. My questions are: Is it generally possible to simulate the flushing of toilets including solid parts (feces)? This would be a "3 phase" problem (water, solid and air at the surface), in my opinion. Which program would you suggest for solving this problem? I have solutions from CD Adapco, Ansys, CF Design and Mentor Graphics in my eyes. Also the program should have an interface or the possibility to use CATIA V5 models. I think, this is a tough job, isn´t it? Thank you in advance for your help. Best regards Sebastian |

Hi again,
has no one an idea? Or just some hints for me on which points I have to look by choosing the software. Thanks Sebastian |

I would try it with a particle based solver. You might check xflow.

You could adopt the diarrhea hypothesis, then you would eliminate the solid issue.
Sorry, just kidding. |

Wouldn't you rather conduct real world experiments instead of simulations?

Previous investigations suggest that it is a 2 phase flow,
Google using the following search criteria "slug flow Toilet flushing cfd" good luck |
