... were evaluated on several unseen test cases. The resulting predictions of efficiency and mass flowrate demonstrated strong correlation with CFD results and experimental test results. The hybrid meanline modeling method therefore displays great potential in wide range radial turbine performance...

... be referred in Ref. [ 21 ]. A turbocharger radial turbine is employed for the validation of the analytical model. Main geometrical parameters of the turbine are listed in Table 1 . The 1D unsteady model is established based on actual geometries of the turbine. Specifically, the length and the volume...

...Nicolas Binder; Yanncik Bousquet; Florian Hermet; Jérémie Gressier Radial turbines are frequently submitted to unsteady inlet flows, for example, in turbocharging applications. Complex flows dominated by waves propagation take place, and advanced methodologies are required. Such complexity...

...Ahmed Farid Ayad Hassan; Markus Schatz; Damian M. Vogt A novel control technique for radial turbines is under investigation for providing turbine performance controllability, especially in turbocharger applications. This technique is based on replacing the traditional spiral casing with a multi...
