A comparison of axial turbine loss models for air, sCO2 and ORC turbines across a range of scales
International Journal of Thermofluids, 2022 Loss models are used to evaluate the aerodynamic performance of axial turbines at the preliminary design stage. The commonly used loss models were derived for air and steam turbines and have not been sufficiently investigated for turbines working with ...

Perspectives on the Treatment of Secondary Flows in Axial Turbines
Energy Procedia, 2017 A review is presented of the main end-wall treatments for the secondary flows of axial turbines. This encompasses the use of axisymmetric and non-axisymmetric contoured end-walls, the use of fences, and of air injection and blowing. Experimental and numerical results show promise in all these techniques. Interest seems to be drawing towards the use of
