Hello Everyone,
I am doing shrouded propeller analysis for underwater vehicle. To estimate speed and power of propeller at different velocities, I need to plot plot the coefficient of torque and coefficient thrust Versus advance ratio graph. I calculate the resistance produced by vehicle hull body. Now I want to calculate Propeller performance by Fluent and ITTC-1978 performance prediction method, from that I calculate power, initial guess of wake (w) and thrust deduction factor(t) then Calculate (Kt/J^2) now from this how to calculate speed of propeller and open water efficiency. also what is open water case and Hull interaction case ? |
