Abstract: The flow in a 1.5-stage axial turbine is investigated by large-eddy simulations. The focus is on the ingress in the downstream wheel space. Two setups are considered. In the first, the full 360 deg annulus is included on ...

Abstract: The flow in a 1.5-stage axial flow turbine with 16 vanes and 32 blades is investigated by large-eddy simulations with special focus on the analysis of the hot gas ingress through the rim seal into the upstream wheel space. ...
