Stringent emission regulations are driving engine manufacturers to increase investment into
enabling technologies to achieve better specific fuel consumption, thermal efficiency and …

With the widespread application of pulse turbochargers in internal combustion engines,
steady or quasi-steady turbine models are no longer qualified for on-engine turbine …

This paper presents a simplified methodology of pulse flow turbine modelling, as an
alternative over the meanline integrated methodology outlined in previous work, in order to …

This paper aims to provide a detailed understanding of the flow interaction within the
complex geometry of turbine stage coupled with reflection and superposition of the imposed …

The paper attempts to correlate simulations and measurements of turbine performance
under pulsating flows for automotive turbochargers. Under real automotive powertrain …

This paper investigates turbine performance and gasdynamic behaviours of a radial turbine
confronted by pulsating inflow via detailed flow measurement. Firstly, pressure propagation …

Automotive turbocharger turbines usually work under pulsating flow because of the
sequential nature of engine breathing. However, existing turbine models are typically based …

Downsizing the internal combustion engine has been shown to be an effective strategy
towards CO2 emissions reduction, and downsized engines look set to dominate automotive …

The flow through radial turbines in automotive turbocharging applications is inherently
highly unsteady, exhibiting high amplitude pulsations of varying frequencies. This can have …

Estimating correctly the turbine acoustics can be valuable during the engine design stage; in
fact, it can lead to a more optimised design of the silencer and aftertreatment, as well as to …
