A fully Lagrangian DEM-MPS mesh-free model for ice-wave dynamics
Rubens Augusto Amaro Junior, Andrea Mellado-Cusicahua, Ahmad Shakibaeinia +1
This paper develops and evaluates a novel 3D fully-Lagrangian (particle-based) numerical model, based on the hybrid discrete element method (DEM) and moving particle semi-implicit…
Fluid-driven granular dynamics through a consistent multi-resolution particle method
Mojtaba Jandaghian, Ahmad Shakibaeinia
Granular dynamics driven by fluid flow is ubiquitous in many industrial and natural processes, such as fluvial and coastal sediment transport. Yet, their complex multiphysics natur…
Stability and accuracy of the weakly compressible SPH with particle regularization techniques
Mojtaba Jandaghian, Herman Musumari Siaben, Ahmad Shakibaeinia
This paper proposes and validates two new particle regularization techniques for the Smoothed Particle Hydrodynamics (SPH) numerical method to improve its stability and accuracy fo…
Water Vapor: An Extraordinary Terahertz Wave Source under Optical Excitation
Keith Johnson, Matthew Price-Gallagher, Orval Mamer +6
In modern terahertz (THz) sensing and imaging spectroscopy, water is considered a nemesis to be avoided due to strong absorption in the THz frequency range. Here we report the firs…
