I have designed a turbine blade and am in the process of simulating the results using the Flow Simulation Add-in. Due to the fact that the software cannot simulate the actual rotation of the blade, I have had to select a range of (forced) angular velocities of the air travelling around the blade, to simulate the turbine moving. The Computational Domain has been set with an initial velocity of 100 knots. I am having it calculate the torques acting on the blade at each of the points within the range of forced angular velocities using a 'What If' Parametric study.
What I am struggling with is how to then use the resulting polynomial curve to determine the free-spinning angular velocity e.g. the unforced angular velocity of the turbine at 100 knots. Which I will then plug back into the simulation to determine the torque of the turbine at 100 knots and thus the power. I am unsure of how to determine this free spinning angular velocity from the curve and am unsure if I am using the correct inputs/outputs to determine it. I am unsure of the relationship that the unforced angular velocity has to any of the results that the software can produce based purely on the velocity of the air and the turbine design as inputs.
Any help, sources or advice would be most welcome.
