Pitches value problem
I want to excute a transient simaulation of an isolated transonic Rotor 37 using ANSYS CFX 11 with rotation along one pitch, but the value of pitches displayed by the solver doesnt correspond to that i specified.
my setup is as fellow :
- Rotor 37 design speed = 17188.7 rpm = 1800 [rad/s]
- 36 blades ===> 1 pitch = 2*3.1416/36 = 0.1745333 [rad]
- total time to rotate along one pitch = 0.1745333/1800 = 9.7e-5 [s]
- if i choose 100 time steps ===> DT = 9.7e-5/100 = 9.7e-7 [s].
I should see in each time step an increase of pitches by 0.01, but it is not the case !!!!!!
what it can be the problem ????? and I could not get convergence????
any advice is very welcome.
