Extract

A numerical method is described for predicting incompressible, attached flow round multiple-section aerofoils at high Reynolds number. Interaction between wakes and boundary layers is not accounted for, but the method is nevertheless suitable for optimisation of design in the take-off condition. The solution is obtained in three steps:

  1. (i) The calculation of the outer, potential flow using a conventional Kutta condition for each aerofoil section.

  2. (ii) The calculation of viscous boundary layers and wakes.

  3. (iii) The combination of the inviscid and viscous solutions to effect proper matching at the edges of the boundary layers and wakes and a more accurate specification of the circulation in the inviscid flow.
