Large Eddy Simulation Modeling of Flashback and Flame Stabilization in Hydrogen-rich Gas Turbines using a Hierarchical Validation Approach
Performer: University of Texas at Austin
Project No: FE0007107
The proposed work at the University of Texas aims to develop large eddy simulation (LES) models for simulating high hydrogen content (HHC) gas turbine combustion, with specific focus on premixing and flashback dynamics. The project is divided into three components: (1) LES model development using direct numerical simulation (DNS) and canonical experimental data, (2) targeted experimental studies to produce high quality mixing and flashback dynamics under engine relevant conditions, and (3) validation of LES models using a validation pyramid approach and transfer of models to industry using an open source platform.
Jet flames in crossflow with different levels of premixing. The fuel is 70% CH4 +30% H2. From left to right: non-premixed, jet fluid diluted by 25% (volume basis) with air, and jet fluid diluted by 50% with air.
