Abstract Gas explosion is a process involving complex hydrodynamics and chemical reactions. In order to investigate the interaction between the flame behavior
and the dynamic overpressure resulting from the explosion of a premixed gasoline-air mixture in a confined space, a large eddy simulation (LES) strategy
coupled with sub-grid combustion model has been implemented. The considered
confined space consists of a long duct and four branches symmetrically distributed on both sides of the long duct. Comparisons between the simulated and
experimental results have been considered with regard to the flame structure,
flame speed and overpressure characteristics. It… More >
