... . Note that the radial clearance between the teeth of the labyrinth seal and the end-wall was identical for both cases. The contour plots in Fig. 7 show the time-averaged and circumferentially averaged swirl ratio field from the numerical simulations. In-plane streamlines are superimposed...

...Thomas Hösgen; Matthias Meinke; Wolfgang Schröder 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. Two setups with different...
