摘要

Duct-vented gas explosion was simulated based on k-ε turbulence model and Eddy-Dissipation-Concept (EDC) model in this paper. Flame propagation process during venting was studied to analyze the mechanisms of the severer explosion severity compared with direct venting. Effect of vent duct quantity was also studied. It is shown that explosion in duct leads to the higher maximum reduced pressure (Pred); frictional drag and gas column inertia play minor roles in intensifying explosion violence; use of double ducts can reduce explosion severity.
