Replies: 13 Problems about propeller simulation Views: 4,337 Posted By duguyoudi Problems about propeller simulation I want to analyze a ten-bladed thruster propeller. I found that thrust calculated is just 50% of which I predicted. I used rotating reference frame for the propeller-fluid domain where I gave the...
