Comparison of Flame Propagation Statistics Extracted from Direct Numerical Simulation Based on Simple and Detailed Chemistry—Part 1: Fundamental Flame Turbulence Interaction

In the present study, flame propagation statistics from turbulent statistically planar premixed flames obtained simple and detailed chemistry, three-dimensional Direct Numerical Simulations, were evaluated compared to each other. To this end, a new database was established encompassing five different conditions on combustion regime diagram, using nearly identical numerical methods same initial boundary conditions. A discussion of advantages limitations both approaches is provided, including difference in carbon footprint for establishing database. It shown that displacement speed their interrelation with curvature tangential strain rate are very good qualitative reasonably quantitative agreement between chemistry Simulations. Hence, it concluded simulations should retain importance future research, environmental impact high-performance computing be carefully chosen relation goals achieved.
