Hi

We worked before with Fluent 6.0. In this version we can set up the bubble radius and tne density of bubble. Now we have the 6.1 version and we can't set up the radius bubble and the density. Does somenone know how can we do with the new version to use the bubble radius and the density.

Thanks

Hi! Fluent 6.1 has different cavitation model than fluent 6.0 (check fluent documentation). I think it's possible to write to fluent distributor to provide you the old cavitation model that will work in 6.1 version. However I think the new cavitation model is a lot better than the old one - it's a lot more stabile and all the parameters that you have to give are measurable (frankly nobady really knows the number of bubbles per m^3 - i found values from 10000 to 10^9, the same thing is with bubble radius - from 10-5m to 3*10-4m):
