Effects of Contact Force Model and Size Distribution on Microsized Granular Packing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Granular packing of microsized particles with different size distributions and contact force models is studied using discrete element method (DEM). Three kinds of size distributions, monosized, uniform, and Gaussian, with ...
Atomistic Continuum Hybrid Simulation of Heat Transfer Between Argon Flow and Copper Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simulation work aiming to study heat transfer coefficient between argon fluid flow and copper plate is carried out based on atomisticcontinuum hybrid method. Navier–Stokes equations for continuum domain are solved ...
Melting, Vaporization, and Resolidification in a Thin Gold Film Irradiated by Multiple Femtosecond Laser Pulses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Melting, vaporization, and resolidification in a gold thin film subject to multiple femtosecond laser pulses are numerically studied in the framework of the twotemperature model. The solidliquid phase change is modeled ...
Hybrid Atomistic-Continuum Simulation of Nanostructure Defect-Induced Bubble Growth
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effects of nanostructured defects of a copper solid surface on bubble growth in liquid argon have been investigated through a hybrid atomistic-continuum (HAC) method. The same solid surfaces with five different nanostructures, ...
Analysis of Cohesive Microsized Particle Packing Structure Using History-Dependent Contact Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Granular packing structures of cohesive microsized particles with different sizes and size distributions, including monosized, uniform, and Gaussian distribution, are investigated by using two different history dependent ...
Development of a Hybrid Lagrangian–Eulerian Model to Describe Spark-Ignition Processes at Engine-Like Turbulent Flow Conditions
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: With the engine technology moving toward more challenging (highly dilute and boosted) operation, spark-ignition processes play a key role in determining flame propagation and completeness of the combustion process. On the ...
