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.

Cílem příspěvku je popsat proces měření a vyhodnocení získaných dat pro zjištění vlastností turbíny turbodmychadla se dvouvstupovou skříní. Specifikem měření dvouvstupových turbín je nutnost oddělení sekcí. Je nezbytné řídit rozdílné podmínky v sekcích pro dosažení parciálního ostřiku oběžného kola turbíny. Získané výsledky tvoří základ pro kalibraci vyvinutého fyzikálního 1-D modelu radiální turbíny se dvouvstupovou skříní.
