2022, FuelCitation Excerpt :According to this, the flame propagation characteristics of methane/air mixtures in obstructed ducts need to be investigated [15–21]. To gain insight into the influence of obstacles on the flame behaviors of combustible gas explosions, previous studies have focused on the effects of obstacle characteristics such as obstacle structures, obstacle numbers, and blockage ratio (BR) on flame morphology, flame velocity, and overpressure variations [22–26]. For example, the obstacles with mutated edges like the square obstacles will greatly accelerate the flame propagation, whereas obstacles with smooth surfaces like the circles induced flame acceleration to a lesser extent [27–29].
