I am calculating the total moment of a Vertical Axis Wind Turbine in 2D as shown below (experimenting with only one blade).
I set up the CFD with sliding mesh (grey area) in trasient simulation
I have a question: When I calculate moment coefficient, does ANSYS Fluent already take into account the relative velocity between the blade (rotational velocity) and the wind (inlet velocity)?
To make it clearer, let's denote: V(a/g): Velocity of air with respect to (wrt) the ground a.k.a inlet velocity, V(t/g): Velocity of turbine wrt the ground a.k.a tangential velocity and V(a/t): Velocity of air wrt turbine
V(a/g) = V(t/g) + V(a/t) - In vector notation
In other words, does ANSYS Fluent automatically calculate Cm, Cl and Cd based on the relative velocity (Va/t)?
I can extract Cm versus flow time but I'm not sure how ANSYS Fluent calculate Cm (as well as Cd and Cl) when there is a sliding mesh involved.
Thank you very much.
