Profile loss and turbulence modelling in radial outflow turbine cascades [PDF]
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.

Performance tests of the radial outflow reaction turbine for geothermal applications [PDF]
, 1978 A unique pure reaction turbine, for geothermal applications, has been developed. This radial outflow reaction turbine (RORT) is designed specifically to produce power from the expansion of saturated or compressed liquid at temperatures of less than 180/sup 0/C. In the tests reported here the highest efficiency measured was 32.7%, clearly below the peak

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 ...
