hello everybody
I want to simulate a propeller is rotating in water in two situation in fluent. First, noncavitating Second, cavitating propeller.
I'm new to such these problems and I want to know that:
1.What is better for this problem? rotating refference frame or sliding mesh?
2. Is cavitation for rotating propellers steady or unsteady? Imean how should i model the cavitation in a steady or transient manner?
3. After simulation how could i calculate the thrust and thrust cefficient of the propeller?
4. What is the AREA in refference values? because of thrust and other coefficients.

I SIMULATE A PROPELLER DTMB4119 IN A STEADY MANNER WITH ROTATING REFFERECE FRAME BUT I GET FOR EXAMPLE A Cp DIAGRAM LOOKLIKES EXPERIMENTAL DATA BUT the numbers are bigger or i get the thrust coefficient 0.2 instead of 0.15.


I will be grateful if anyone helps me...
