    Detailed Thermodynamic Models of New/Unconventional Multi-Scroll Turbine Design(s): optimized designs

  • Original language description

    The models are based on CFD approach using 3-D CFD. The focus is put on 3-D CFD while considering the complete 3-D geometry and a movable rotor. Different unconventional multi-entry turbomachinery has been tested and evaluated. It is confirmed that 3-D CFD is capable of correct unsteady performance prediction, however the calculations are very time demanding. Different turbine designs are being evaluated and optimized using simplified 1-D tool as a basis. The target is to improve overall turbine performance under highly unsteady operation (6-cylinder ICE with 2 exhaust branches, each connecting 3 cylinders). Complex support tools were created to propose initial turbine shape (based on simplified 1-D CFD) and detailed thermodynamic evaluation tool based MS Excel.

    Rozsáhlá databáze výsledků 3-D CFD RANS simulací turbin/kompresorů za různých pracovních podmínek včetně nestacionární pracovního cyklu. Databáze je tvořena výstupními soubory programu AVL FIRE (obecný 3-D CFD nástroj; Linux/Windows). Je řešena kompletní 3-D CFD geometrie s pohyblivým rotorem. Statistické zpracování vybraných integrálních/lokálních vlastností pak bylo provedeno v programu MS Excel. Počáteční návrh tvaru je realizovám pomocí zjednodušeného 1-D CFD nástroje.
