rotation region and cavitation problem 2D

[javier101191]

Hi, i have a problem with a 2D geometry, first of all, i dont know if i am drawing by the right way the rotation region, because, i have 3 materials in real, a rotor(in), the fluid (water) and then the stator (out).

When i look at the results, in the viscosity, the rotation region part  has a different viscosity than the water part, and i though that ratation region took all the fluid properties, isn´t it??.

In the problem i want to see the pressure distribution, and look if i can force cavitation. With 1500 rpm i think it should cavitate. Has the problem a good setup?? ADV5, 3 degrees per time step, cavitation enabled, etc..

Lot of thanks

Hi,

Is this the same model as the thread here? http://forums.autodesk.com/t5/simulation-cfd/cavitation-2d-geometry/m-p/5335667#M5813

Wondering if it might be better to keep it all in one place, or you have to collect helpers each time 🙂

sorry!!, i couldnt find it, i will post it there! 😉
