This paper investigates blast mitigation mechanism of stratified layered particles inside straight tube. Due to difficulty of steady-state analysis of blast waves, the configuration of numerical target is simplified to the propagation of vertical shock wave. In addition, CFD results are compared with Curved Shock Theory (CST) to analyze the flow field and mitigation mechanism. The shock wave is curved and mitigated due to the effect of drag force at the bottom of tube in CFD results, and the flow field is well predicted by CST. Therefore, mitigation of shock wave can be explained by shock propagation in curved form.
