ABSTRACT:
A series of numerical simulations of blast wave/target interaction was performed to match a series of experiments conducted at the Centre d'Etudes de Gramat (CEG), France. The experiments that were modeled involved a square; two-dimensional block target positioned in the vertical center of

a shock tube test section and subjected to non-decaying blast waves of various amplitudes. The results of the inviscid second order hydrodynamic advanced research code (SHARC) and the viscous USA-RG2 code simulations are compared to experimental1y measured pressure histories. Particular emphasis is placed on the accurate modeling of vortex formation and evolution, which influences the aerodynamic loading of the target. The viscous and inviscid results are directly compared to determine the most accurate method of modeling both diffraction and drag phase blast loading of targets. Show Less
