Error in rans deflection in far wake?

[AndiTUM]

Hello again,

After comparing your rans deflection model to our implementation at TUM, I observed differences in the far wake. The problem lies in equation 7.4 of the paper of Bastankhah and Porté-Agel from 2016.

In rans_deficit_deflection.m line 93 the equation is given:
FW_delta = obj.delta_x0+obj.theta_C0*(obj.rotorRadius/7.35)*sqrt(sqrt(det(obj.C/((diag([obj.ky obj.kz])*obj.ct)^2))))*(2.9+1.3*sqrt(1-obj.ct)-obj.ct)*lnTerm.';

I think it should be written
FW_delta = obj.delta_x0+obj.theta_C0*(obj.rotorRadius/7.35)*sqrt(sqrt(det(obj.C/((diag([obj.ky obj.kz])*sqrt(obj.ct))^2))))*(2.9+1.3*sqrt(1-obj.ct)-obj.ct)*lnTerm.';
that the code correctly represents eq 7.4 with sqrt(obj.ct) instead of just obj.ct.
Please check this equation.

Best,
Andi
