Popis: Uncertainty-quantification-driven simulations of an explosive experiment are performed to minimize the flow prediction error in the PBXN-5 detonation products and air flow. The global sensitivity response of JWL model parameters based on simulation transverse shock position is given by main sensitivity index over time. The calibration of explosive products model parameters based on experimental shock position data produces good agreement between simulation and experimental results.
