Analysis of radial-outflow turbine design for supercritical CO2 and comparison to radial-inflow turbines [PDF]
Energy Conversion and Management, 2022 Cycles using supercritical carbon dioxide have been recognized as potential future power technology. However, the turbines in these systems tend to experience very high rotational speeds and entail small physical sizes, which can affect on the overall feasibility.

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.
