Abstract There are many applications of radial-flow turbomachines, but this paper deals particularly with radial turbines for gas-turbine use. The possibility of building a multistage inflow turbine of a type in which all the stages are carried on a single rotor disk is examined.

Losses in Radial Inflow Turbines
Journal of Fluids Engineering, 1976A study was conducted to determine experimentally and theoretically the losses in radial inflow turbine nozzles. Extensive experimental data were obtained to investigate the flow behavior in a full-scale radial turbine stator annulus. A theoretical model to predict the losses in both the vaned and vaneless regions of the nozzle was developed.

The radial, or centripetal, turbine is used for very small flows, where it is cheaper and simpler to make than an axial flow turbine. It is used in the smallest gas turbine engines, as in some automotive or fire pump or other portable applications, and is used extensively in the smaller turbochargers.

The Characteristics of Radial Turbines for Small Gas Turbines
Volume 6: Turbo Expo 2003, Parts A and B, 2003Inward flow radial and mixed flow turbines are effectively utilized in both small gas turbine auxiliary power units (APU’s) and turbochargers, where moderately high levels of efficiency can be readily attained with simple cast components, less sensitive to blade end-gap clearances than axial turbines.

Effects of Inlet Conditions on the Turbine Performance of a Radial Turbine
Volume 6: Turbomachinery, Parts A, B, and C, 2008For a turbocharger working under internal combustion engine operating conditions, the flow will be highly pulsatile and the efficiency of the radial turbine will vary during the engine cycle. In addition to effects of the inflow unsteadiness, there is also always a substantial unsteady secondary flow component at the inlet to the turbine depending on ...

A laminar flow rotor for a radial inflow turbine
29th Joint Propulsion Conference and Exhibit, 1993The state of the boundary layers on the blade surfaces of the rotor of a radial inflow turbine has been investigated using surface-mounted hot-film anemometers. The boundary layers are shown to be laminar or intermittently turbulent at the design flow condition.

A cooled laminated radial turbine technology demonstration
18th Aerospace Sciences Meeting, 1980A low-cost, high-temperature radial turbine has been developed demonstrating the technology required to manufacture a small, cooled turbine using photoetched laminates bonded together to form a complete wheel. An advanced long-life, high-performance turbine design is described which uses an iterative optimization procedure to provide a balanced ...

The Radial Turbine as a Ceramic Component
Volume 1B: General, 1978In sizes suitable for automotive gas turbines, the small radial turbine has component efficiency equal to that of the axial type, is less sensitive to the effects of tip clearance, and translates more readily into the ceramic medium with minimal aerodynamic compromise.

The flow path in radial turbines may be centrifugal as in the Ljungstrom design or, more commonly, centripetal as in most of the machines found in both water power installations and in gas power generation plant. The two types of flow path are illustrated in Figs 8.1, 8.2 and 8.3.
