RISEffects of Initial Perturbations in the Early Moments of an Explosive Dispersal of Particles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent experiments have shown that when a dense layer of solid particles surrounding a highenergy reactive material is explosively dispersed, the particles cluster locally leading to jetlike patterns. The formation of these ...
A Kriging Surrogate Model for Computing Gas Mixture Equations of State
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate simulation of the complex flow following the detonation of an explosive material is a challenging problem. In these flows, the detonation products of the explosive must be treated as a real gas while the surrounding ...
Early Time Evolution of Circumferential Perturbation of Initial Particle Volume Fraction in Explosive Cylindrical Multiphase Dispersion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When an annular bed of solid particles that surrounds a cylindrical high-energy explosive core gets radially dispersed after detonation, the expanding front of particles undergoes instabilities. One of the possible causes ...

Uncertainty Reduction for Model Error Detection in Multiphase Shock Tube Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uncertainty quantification (UQ) is an important step in the verification and validation of scientific computing. Validation can be inconclusive when uncertainties are larger than acceptable ranges for both simulation and ...
