Hi,
I am trying to simulate 2D savonius rotor wind turbine. but i have done every thing good so far expect the post processing one. I am trying to calculate the Drag coefficient and Lift coefficient of my work. The way which i am using right now. Report > Forces> then i am going to x and y direction forces. Then converting the the forces in to tangential force and normal force using those two Equation : Fn= Fx*SinA+Fy*CosA Ft=-(Fx*CosA-Fy*SinA) Here is A is 0 for balde1, 120 for blade2, 240 for blade 3 . After that i am using the formula Cd=Fd/(1/2*p*U*U*A) Cl=Fl/(1/2*p*U*U*A) to calculate drag and lift. But i am not getting the value which i am suppose to get for this work. Am i going to the right way ?? I have attached jou file i am not sure you will be able to see that please let me know. i cant upload the cas file as the size is more than 97 kB. thanks in advance Kirit |

Hi kirit!
I doing the same problem to u. But i don't know how to Apply the inlet and outlet. How can we apply the angular velocity of rotor what the unknown of turbine problem? |

Hi
ok, very long back i was done simulation in CFX-11 Boundary conditions: Inlet:Stagination Temperature and Velocity(sunsonic) Outlet: static pressure(subsonic) K&e model,boundary layer 2mm
