3-D CFD model(s) of unconventional turbine - status 2021

Popis výsledku v původním jazyce

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). The detailed CFD models (developed within this workpackage during 2019-2021) provided a lot of data and experience. The majority of these models are based on 3-D CFD approach which is supposed to provide detailed thermodynamic data. However, advanced SW tool based on simplified 1-D CFD was created (in MS Excel) to allow for fast initial design of turbine inlet (this includes all the inlet channels, a spiral and possibly guide stator vanes) before it is applied to time consuming 3-D CFD calculations. The tool is also used for preliminary design optimization of turbine inlet design. Additional tools and post-scripts were developed to allow for detailed analysis of huge amount of CFD data (each design version is represented by 1.8TB of data; up to now 11 variants were analyzed).

Technické parametry

Rozsáhlá databáze výsledků 3-D CFD RANS simulací turbin 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.
