Profile loss and turbulence modelling in radial outflow turbine cascades
European Conference on Turbomachinery Fluid Dynamics and Thermodynamics, 2023 Radial outflow turbines (ROTs) offer an alternative for single stage high-work axial turbines in steam and organic Rankine cycle applications. Their main benefits are lower Mach number levels, improved design and off-design performance and improved capability to handle high volume flow rates.

Loss generation in radial outflow steam turbine cascades [PDF]
European Conference on Turbomachinery Fluid Dynamics and hermodynamics, 2017 Due to the fact that noise emitted by aero engines became a very important issue especially during the last few years, acoustic measurements were carried out downstream of the low-pressure turbine in a two-stage two-spool test turbine. The aim of these analyses was to determine the influence of small geometry changes in the flow path of the rig under ...

Numerical optimization of air breathing radial outflow turbines [PDF]
European Conference on Turbomachinery Fluid Dynamics and hermodynamics, 2019 Small air driven alternators serve as a practical solution to be a power source for miniature electronic equipment. An air-breathing radial outflow turbine can be easily manufactured and implemented to a variety of terrestrial and aerial vehicles for auxiliary power generation. The flow characteristics of such turbines need to be understood in order to
