Direct numerical simulation of a PMMA–G O 2 slab burner: Experimental validation and extension to Marxman theory

Key Points

• The experimental validation confirms the accuracy of the direct numerical simulation approach for the PMMA–O2 slab burner.
• Numerical simulations revealed complex flow dynamics and combustion characteristics under various conditions.
• Assessment includes rigorous comparisons with existing theories, particularly the Marxman theory, to refine modeling techniques.
• This work supports enhanced predictive capabilities in combustion simulations, with broader implications for optimizing burner designs.
