D2.3 – Report on simulation framework for H2/O2 and H2/air combustion

This report presents the development of a hierarchical modeling framework designed to predict the effects of thermo-diffusive instabilities in turbulent H2/O2 flames and H2/air flames. It serves as a summary of the activities conducted within Task 2.3 of the HyInHeat project. Thermo-diffusive instabilities are a critical challenge in hydrogen flames, significantly influencing combustion performance by increasing the risk of blow-off and flashback while also increasing pollutant emissions. Accurate predictive modeling is, therefore, essential for the design and the retrofitting of combustion systems that operate with H2.

The modeling framework developed in this task is designed for integration into full furnace simulations, including both large-eddy simulations (LES) and Reynolds-averaged Navier-Stokes (RANS) simulations, which are planned for Work Packages (WP) 5 and 6. The framework relies on the kinetic mechanisms provided in WP 1.3 for both model development and validation.

Task 2.3 is a collaborative effort involving the following partners: RWTH-ITV, RWTH-IOB, and BSC
