abstract

The purpose of this contribution is to report on the aerodynamical performance calculations carried out around single stage high pressure turbines including rotor blade tip clearance effects. Three different turbine configurations are considered: a low lift case with two different tip gap heights and a high lift case. A multistage approach based on the ONERA-Snecma 3D Navier-Stokes code CANARI is used to investigate the turbine flow behaviour. The computational results are compared with experimental data and with results obtained by single blade row simulations.
