INFLUENCE OF BML MODEL PARAMETERS AND OBSTACLE EFFECTS ON THE TURBULENT REACTION RATE OF PREMIXED HYDROGEN FLAMES

Analyzing flame behavior through numerical modeling is essential for advancing combustion studies. This work presents a numerical study of turbulent premixed hydrogen flame propagation using the STOKES software. The methodology employs Computational Fluid Dynamics (CFD) simulations with the Reynolds-Averaged Navier-Stokes (RANS) approach and the Bray-Moss-Libby (BML) combustion model. The primary focus consists of a parametric sensitivity analysis of fundamental terms in the turbulent reaction rate in the BML model: the shape factor, the orientation factor, and the length scale constant. Through an experimental design, the impact of variations in these parameters on flame propagation and speed is analyzed.
