- Abstract:
-
At engine representative flow conditions a significant portion of flow over a high-pressure turbine blade tip is transonic. In the present work, the choking-flow behavior and its implications on overtip leakage-flow loss generation are computationally analyzed. An extensively developed Reynolds-averaged Navier-Stokes code (HYDRA) is adopted. First, a high-speed linear-cascade validation case is introduced, and the computations are compared with the experimental data to identify and establish ...
