3-D CFD aerodynamic model of HP turbine
Original language description
The modelling approach is based on application of different tools. Engine model is based on detailed 1-D CFD approach for the case of highly-turbocharged 2-stage gas SI ICE (the model was developed within previous phase of the NCK1 project during 2019-2020). The model provides initial/boundary conditions for turbine operation. Detailed 3-D CFD model is based on detailed 3-D CAD/CAE data and it features full-scale geometry with movable rotor and turbulent transient compressible flow solver (suitable for high Mach number regimes). This allows for detailed locally-averaged flow analysis to identify possible improvements of turbine operation. The model was applied to both steady-state operation (in terms of boundary conditions; the flow solution is always unsteady) and fully transient one. The package was extended by in-house tool to perform detailed analysis of the results (both steady-state operation and ICE-like transient one). Based on that, more than 12 design variants were tested virtually. This was a base for selection of final 2 ones to be manufactured and tested (both steady-state and transient on gas SI ICE).

Technical parameters
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 pomocí vlastních SW nístrojů v programu MS Excel.
