Hi all,
I am new to CFD .. I want to know the volume fraction of sand in water in a stir tank with 4 baffles and one PBT propeller inserted from bottom. I am using Eulerian,K-Epsilon,MRF model for it.. for that i need to create a volume around the impeller as rotating reference .and baffles and rest part as stationary reference frame... I am confused at the following points...
1. do i need to create to separate volumes for sand and water for initial postition...
2. If this is the case then how would i create MRF cylinder n my main tank model? Please some one guide me on this issue...
I will be very thankful
