Abstract
This paper presents a hybrid grid strategy for the CFD modeling of complex technological effects which can be encountered on turbomachinery applications. It consists in mixing within the computational domain structured and non structured zones which are connected with conformal matching frontiers. The main channel flow path is meshed with a classical structured approach, while non structured grids enable to mesh the technological components. The application of this grid strategy with the ONERA CFD code elsA is illustrated on two industrial applications: a multi-row film-cooled turbine blade and a multistage compressor including labyrinth seals.
