Integration of CFD and thermal stress analysis for turbochargers

摘要

Development of turbochargers requires thermal stress analysis based on the. temperature distribution estimated by CFD. The turbine housing of the turbocharger has complicated geometry with free form surface and is used under severe conditions with high temperature gas flow. The development period needed to integrate these analyses must be reduced. Effective analyses for new product development using 3D model data require rapid and efficient calculation processes. In this paper, the effects andfuture objectives of analyses designed to integrate CFD and FEM for the turbine housing of turbocharger are described.
