Nowadays the optimization using computational fluid dynamics (CFD) plays an important
role in the design process of turbomachines. However, for the successful and productive …

The aim of this numerical study is to characterize the flows of a twin-entry radial turbine and
the development of Dean vortices in its asymmetrical volute, as well as to examine the …

Since the turbocharger turbine plays an important role in determining the engine
performance, how to model and extrapolate mass flow characteristics of the turbocharger …

Turbocharger noise has become a major concern in downsized automotive engine
development. In this paper, the analysis is focused on the whoosh noise produced by the …

The ducted fuel injection strategy is a method that significantly reduces soot emissions in
direct injection compression ignition engines. Fuel is injected into the combustion chamber …

Due to the power consumption restriction of the turbocharger compressor, common turbine
maps are rather narrow. To extrapolate them, reliable physical submodels are needed that …

The current paper presents a flow behaviour analysis of twin-entry radial turbines by means
of experimental measurements and computational fluid dynamics (CFD) simulations. The …

Aircraft intermittent combustion engines often incorporate turbochargers adapted from
ground-based applications to improve their efficiency and performance. These …

This paper presents the development and validation of a one-dimensional radial turbine
model able to be used in automotive turbocharger simulations. The model has been …

Many recent studies show that the performance of Savonius turbines can be considerably
increased by using wind deflectors. Axisymmetric deflectors are particularly interesting; they …
