Samenvatting:
For the numerical prediction of the aerodynamic
forces on wind turbine blades, a viscous-inviscid
interaction method is applied. From a discussion
on the interaction methods, focussing on their ability
to simulate separated flows, it follows that the
quasi-simultaneous interaction method is the most
suitable. The method employed here uses only
the local influence of the external flow, resulting
in an algebraic expression for the interaction-law
equation. The method is applied to a model problem
for a three-dimensional steady, incompressible,
turbulent flow over a flat plate. For attached
flow the quasi-simultaneous method converges to
the same solution as a flow solver using a direct
interaction method.
