Default stirred tank Modeling
Randheer Yadav
Posts: n/a
Hi, I am modeling a stirred tank fitted with rushton turbine. I am trying MRF and Sliding mesh techniques. The doubts which i have is, 1) How to fix the impeller rotation direction (clockwise /anticlockwise)? 2)When using MRF Should the rotating speed be supplied for both impeller and the inner fluid zone (In my case impeller speed is 270 rpm)or only to the impeller? 3)When using SM should the impeller speed be given only to the grid associated with the inner fluid zone. and impller will remain stationary? please help me.
