platform (Li et al, 2016), this second article focuses on assessment of gas explosion by using
Computational Fluid Dynamics (CFD). Gas explosion simulations are carried out to evaluate
the explosion overpressure mitigating effect of safety gap. The Data-dump technique, which
is an effective tool in resetting turbulence length scale in gas explosion overpressure
calculation, is applied to ensure simulation accuracy for the congestion scenario with safety …
