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: In order to analyze the interaction of multiple rows of film cooling holes in flows at adverse pressure gradients, largeeddy simulations (LESs) are performed. The considered threerow cooling configuration consists of ...

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. ...
