Three-dimensional viscous rotor flow calculations using a viscous-inviscid interaction approach. A three-dimensional viscous-inviscid interaction analysis was developed to predict the performance of rotors in hover and in forward flight at subsonic and transonic tip speeds. The analysis solves the full-potential and boundary-layer Author: John O. Bridgeman and Ching S. Chen. A three-dimensional viscous-inviscid interaction analysis was developed to predict the performance of rotors in hover and in forward flight at subsonic and transonic tip speeds. The analysis solves the full-potential and boundary-layer equations by finite-difference numerical procedures. Calculations were made for several different model rotor configurations. In the three-dimensional case, various researchers have previously implemented a viscous–inviscid coupling using the strip theory approach. Sørensen combined a three-dimensional finite-difference boundary layer solver with a set of two-dimensional panel segments for solving the flow past a Cited by: Viscous–inviscid interaction is the fastest method in computational fluid dynamics available for airfoil design and analysis that is able to capture viscous effects on the flow.

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 .

The solver is based on an unsteady three-dimensional free wake panel method which uses a strong viscous-inviscid interaction technique to account for the viscous effects inside the boundary layer. Viscous/inviscid interaction procedures consist usually of coupling potential flow and boundary layer calculations. Get this from a library!
