Abstract
As a result of the engine-downsizing trend that has characterized the last decades, turbo-charging has taken a central role in the automotive market. In this work the software GT-Power was used to perform a one-dimensional modelling analysis of an engine with two different turbine configurations: mono-scroll and twin-scroll. The main focus was on the latter, for which performance maps provided by suppliers and measured in steady state conditions do not allow to fully catch physical phenomena such as the cross-flow occurring between the two scrolls before the turbine wheel. In this study two different modelling approaches were considered to evaluate which of the two allowed a better matching with experimental results. As outcome of this study, it was found that the best results were obtained when using the modelling approach with only one performance map referring to equal admission conditions.
