Evaluation of Experiments on a Twin Scroll Turbocharger Turbine for Calibration of a Complex 1-D Model

Abstract

The goal of the contribution is to describe the process of measurement on a twin entry turbocharger turbine, and evaluation of obtained data. A specific feature of the twin entry turbine measurement is the separation of turbine sections. It is necessary to control different conditions in each section to achieve partial admission of the turbine impeller. The results are fundamental for the calibration process of a developed physical 1-D model of a radial turbine with twin scroll.
