Hi everyone,
I’m trying to calculate induction and forces on a wind turbine (modeled using ALM) using the velocities obtained from CFD. The domain is set in such a way that zdirection is streamwise (flow) direction, and x as well as y (xy plane is where rotor plane) are tangential directions. I was hoping if someone could clarify a few points:

Does the following relation for tangential velocity hold true → V_tan = sqrt(Vx_r^2 + Vy_r^2) + omegarR? where Vx_r is the xvelocity at a node inside the rotor region, Vy_r is the yvelocity at a node inside the rotor region, omega is the rotation speed of a blade in rad/s, r is the distance of the node from the center of the rotor normalized by rotor radius and R is the rotor radius.

Does the following relation for tangential induction hold true → b = sqrt(Vx_r^2 + Vy_r^2)/(omegarR)?
Thank you in advance!
