Accidental gas explosion is a standard scenario considered in risk assessment for process industries. Blast walls or barriers are an efficient way to reduce the effects of pressure waves originated from an explosion. However, the proper design of a blast wall requires heavy investigation considering real accidental scenarios. CFD-based method can be used for a parametric investigation and for design optimization instead of experimental investigations. Nevertheless, the first CFD codes must be validated versus corresponding experimental data. The purpose of this paper is to present comparison of CFD simulations of propane/oxygen detonation and experimental measurements for small scale explosions.
