Multidisciplinary Optimization of Radial Outflow Turbines With Highly Deformable Blades
Volume 7: Industrial and Cogeneration; Manufacturing Materials and Metallurgy; Microturbines, Turbochargers, and Small Turbomachines; Oil & Gas Applications, 2022Abstract Miniature radial outflow turbines are used to generate onboard power for various aerial devices using the ram effect. The incoming air flow axially entering the inlet conduit of the turbine housing spins the turbine rotor, which may have excessive tip gap and a sizable hub cavity, and radially discharges from the turbine flow ...

Small-scale radial outflow turbines offer a promising alternative to conventional axial turbines, for example in waste heat recovery applications. One of the design challenges with these machines is that the common single flow design approach leads to the need for axial thrust compensation.

Field performance evaluation of geothermal ORC power plants with a focus on radial outflow turbines
Renewable Energy, 2020Abstract The calculation of the performance of an ORC (Organic Rankine Cycle) and its components (in particularly the turbine) is generally not a trivial task because of the lack of a proper instrumentation, the inaccuracy of the available measurements and the uncertainty on fluid thermodynamic properties calculation.

Abstract The design of high-performance small-scale Organic Rankine Cycle (ORC) systems is heavily dependent on optimizing major power plant components. In Radial Outflow Turbines (ROT) greater efficiency is achieved by increasing the rotation speed and decreasing sealing losses by reducing the clearance of labyrinth seals.

Volume 2E: Turbomachinery, 2020
Abstract Radial outflow turbines are an alternative for axial turbines for example in heat recovery applications. They are, however, also often characterized by ultra-low aspect ratios. In these designs, the secondary losses dominate the overall loss share, and under a certain aspect ratio, the secondary structures from the hub and ...

In this study, blade tip leakages were calculated for a Radial Outflow Turbine (ROT) designed for an Organic Rankine Cycle (ORC) at a 150kW power output. Since the turbine blade sizes are relatively very small for low-capacity systems, the leakages through the blade tip clearances considerably affect the turbine isentropic efficiency.

Abstract The radial outflow liquid turbine expander (LTEROF) draws increasing attention for enhancing the efficiency of the liquid CO2 energy storage (LCES) system. However, the detrimental cavitation deteriorates the flow behavior, which demands an in-depth study of the flow physics and then effective attenuation.
