This paper presents an overview of numerical simulations performed at ONERA on representative turbomachinery applications including a wide range of technological effects such as gaps, grooves, casing treatments, cooling holes and fillets. These technological effects are taken into account in the calculations thanks to a chimera technique which is presented.
