Abstract Laser Powder Bed Fusion (LPBF) is commonly used to fabricate metal additive
manufacturing (AM) parts. Advanced sensing empowers the collection of in-situ signals (eg …

We present a comprehensive Euler-Lagrange solver, CP3d, for the direct numerical
simulation of particle-laden flows. The solver can handle one-way, two-way, interface …

Drag force acting on a particle is vital for the accurate simulation of turbulent multiphase
flows, but the robust drag model is still an open issue. Fully resolved direct numerical …

As a typical fluidization technology, Fluid Catalytic Cracking (FCC) is faced with the problem
of catalyst particle abrasion and crushing. However, due to the small particle size of catalyst …

The importance of shear-induced lift, ie Saffman lift, is investigated in two-way coupling point-
particle direct numerical simulation of turbulent channel flow laden with heavy particles. A …

In this paper, we present a multiple-time-step integration algorithm (MTSA) for particle
collisions in particle-resolved simulations. Since the time step required for resolving a …

Point-particle direct numerical simulations of horizontal open-channel turbulence two-way
coupled with inertial particles (St+= 1, 31, 100) are performed to investigate the effects of the …

Fluid-structure-particle interactions in three spatial dimensions happen in many
environmental and engineering flows. This paper presents the parallel algorithms for the …

The settling behavior of polydisperse droplets in homogeneous and isotropic turbulence
was measured by an ultra-high-resolution two-dimensional Particle Image Velocimetry. The …

The data from a particle-resolved direct numerical simulation (PR-DNS) of two-phase over
the sediment bed are used to examine the existing lift force models, including flow shear …
