Numerical simulation on the flame propagation in duct-vented gas explosion: The effect of duct length on the secondary explosion

Duct venting is the most recognized explosion protection technique used in the industry. However, the key problem with this technique is the appropriate design of the duct size for an effective release material to prevent the secondary explosion that can cause further damage to the plant. Factors su...
