Radial Turbines Diagnosis in Turbocharging Application
Journal of Engineering for Gas Turbines and Power, 2014The main purpose of this work is the development of a diagnostic procedure for radial turbines installed on internal combustion engine turbochargers. The study is part of a wider research activity regarding the development of diagnostic systems dedicated to cogenerative engine.

There are two basic types of turbine suitable and used at present in turbochargers, the radial flow and the axial flow. The radial flow turbine is mainly used for small automotive or truck turbochargers; the axial type is commonly used for the large turbochargers applied to medium-speed stationary and railway traction engines and large marine engines.

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.

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 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.

One of the common failure modes of the diesel engine turbochargers is high-cycle fatigue of the turbine-wheel blades. Mistuning of the blades due to the casting process is believed to contribute to this failure mode. A laser vibrometer is used to characterize mistuning for a population of turbine wheels through the analysis of the blade-response to ...

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 ...
