Proc. ASME. GT2022, Volume 10B: Turbomachinery — Axial Flow Turbine Aerodynamics; Deposition, Erosion, Fouling, and Icing; Radial Turbomachinery Aerodynamics, V10BT30A028, June 13–17, 2022
Publisher: American Society of Mechanical Engineers
Paper No: GT2022-82852
.... For a comparably efficient and economical operation over a wide range of operating conditions, partial admission control appears to be a well-suited design option for ORC turbines. However, accurate numerical performance prediction of a partial admitted turbine stage is challenging and requires full annulus CFD...

..., typically realized by a partial admission control, which is challenging to predict numerically. Full annulus computation can only be avoided applying empirical partial admission loss models to conventional full-admission computations. This article aims at assessing the reliability of such a loss model...
