Hi, I’m an aerospace engineer who has working on the designing of propeller for a multirotor. I would like to ask you a question: suppose that I want to design a propeller (10 inches of diameter and 4 for pitch). What approach do you can suggest me to analyze the blade of propeller near the hub in hovering condition, where the Reynolds number is very very low and the beta angle is about 30 degrees? I thought to use xfoil with viscous analysis but in that condition the convergence of solution is never reached. Thank you in advance.
