Design and Optimization of a Radial Inflow Turbine for Use with a Low Temperature ORC
Energies, 2021 This study aims to design and optimize an organic Rankine cycle (ORC) and radial inflow turbine to recover waste heat from a polymer exchange membrane (PEM) fuel cell. ORCs can take advantage of low-quality waste heat sources.

The Design of Two Radial Inflow Turbines [PDF]
Volume 1: Turbomachinery, 1984 Nozzle wakes are a common source of fatigue failures in radial inflow turbines. This paper describes an approach to avoiding these problems, without sacrificing performance or manufacturability, by using a small number of carefully designed nozzle vanes and tuning the rotor blades to avoid nozzle passing resonances.

Dynamic inflow effects in measurements and high-fidelity computations [PDF]
Wind Energy Science, 2018 A wind turbine experiences an overshoot in loading after, for example, a collective step change in pitch angle. This overshoot occurs because the wind turbine wake does not immediately reach its new equilibrium, an effect usually referred to as ...
