Development of the MZM numerical method for 3D boundary layer with interaction on complex configurations
The viscous 3D steady flow problem at high Reynolds number is decomposed into a “Viscous-Defect” VD problem interacted with a pseudo-inviscid problem, the former VD problem being hyperbolic along the boundaries under thin-layer assumptions. Both problems are solved on the whole 3D field, and coupled by the boundary conditions, thus restoring the global elliptic character of the solution. The “Viscous-Defect” problem is solved here by a hybrid field/integral method, involving modelled 3D parametric velocity profiles, discretized in the normal direction. The MZM numerical method of solution of the resulting hyperbolic system of equations has been extended to complex multi-structured configurations. The new method is here applied to wings in attached flows, to ellipsoids at incidence, and to airplane wing-body configurations.
