RISAn Assessment of the Drag Models in the Case of a Shock Interacting With a Fixed Bed of Point Particles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, three-dimensional Euler–Lagrange (EL) point-particle simulations of a shock wave interacting with a fixed bed of particles are carried out. The results from the particle-resolved (PR) simulations are used to ...
Discordance of Tracer Transport and Particulate Matter Fate in a Baffled Clarification System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large eddy simulation (LES) and coupled physical laboratory-scale modeling are performed to elucidate tracer transport and particulate matter (PM) fate in a baffled clarification system. Such baffled systems are common for ...
A Unified Review of Physical Modeling of Heat and Mass Transfer Processes in Frosting and Icing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This review covers issues not addressed in a review paper dealing with icing and frosting before. For example, in icing, we start from the role of nonuniform distribution of large droplets in clouds to the effect ...
Nonlinear Rayleigh–Taylor Instability of a Cylindrical Interface in Explosion Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear growth of instabilities of an outward propagating, but decelerating, cylindrical interface separated by fluids of different densities is investigated. Single mode perturbations are introduced around the ...
On the Use of Symmetries in Building Surrogate Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When simulations are expensive and multiple realizations are necessary, as is the case in uncertainty propagation, statistical inference, and optimization, surrogate models can achieve accurate predictions at low computational ...
Effects 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 ...
