Based on the Euler equations, taking the fluid compressibility andvelocity into account, the RKDG method is introduced into thenumerical simulation of air blast load with large density and pressureratios. Combined with the finite element method and using softwareANSYS/LS-DYNA, shock responses of container ships superstructureunder air blast load are simulated. The structure response and thedamage form of multi-layer container structure subjected to air blastload in different conditions are analyzed. The computationsdemonstrate that proposed method is suitable and robust for solvingflow field with strong shocks and large discontinuities and fluidstructureinteraction in air blast.
