close to the design condition, assuming inviscid and viscous flow. The latter, includes the boundary-layer calculation according to a weak viscous-inviscid interaction formulation. Results are presented for several rotor-blade sections located at different radial positions. The three-dimensional viscous flow was computed using the FLUENT Size: KB. A surrogate-optimization framework using a three-dimensional viscous-inviscid interaction code (MIRAS) for the aerodynamic design of wind-turbine rotors is proposed. To verify the methodology, a model wind-turbine rotor was designed using the proposed method and compared to blade element momentum (BEM) by: Additionally, Ramos-Garcia et al. [5] have presented a viscous-inviscid interaction technique using strong coupling between the viscous and inviscid parts for solving the flow around the blade of. Determining if a flow is (in)viscid in my opinion is best characterized through the Reynolds number, $\mathrm{Re}$. If $\mathrm{Re}\ll1$, the flow may be considered viscous, i.e. Stokes flow. If $\mathrm{Re}\gg1$, the viscous forces may be negligble compared .
