Software tools to design, optimize and evaluate unconventional turbine design(s) under highly pulsating operation - status 2023

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 designed, tested and evaluated. Different turbine designs were evaluated and optimized using simplified 1-D in-house 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). In-house advanced SW tool based on simplified 1-D CFD approch 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, and certain level of an optimization) 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-processing scripts were developed/enhanced to allow for detailed analysis of huge amount of CFD data. Next step was to create a co-simulation between 3-D CFD (turbine) and 0-D/1-D CFD (6-cylinder turbocharged DI ICE) to predict turbine performance under realistic ICE conditions including the interaction with ICE to estimate BSFC benefits/penalties. Such data were analyzed in detail using in-house SW tools. Final step si automation procedure to speed up the process significantly while allowing for automatic optimization of turbina stator design.

Technické parametry

Rozsáhlá databáze výsledků 3-D CFD RANS simulací turbin za různých pracovních podmínek včetně nestacionárních pracovních cyklů. 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 pomocí vlastních SW nástrojů v programu MS Excel. Počáteční návrh tvaru je realizovám pomocí zjednodušeného 1-D CFD nástroje.
