New numerical approaches for modeling thermochemical convection in a compositionally stratified fluid

, 2017
Seismic imaging of the mantle has revealed large and small scale heterogeneities in the lower mantle; specifically structures known as large low shear velocity provinces (LLSVP) below Africa and the South Pacific.

Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment [PDF]

, 2013
A 2D Lagrangian numerical wave model is presented and validated against a set of physical wave-flume experiments on interaction of tsunami waves with a sloping beach. An iterative methodology is proposed and applied for experimental generation of tsunami-

Kidney Transplant Recipients Develop Nasal Mucosal Antibodies to SARS‐CoV‐2 With ACE2‐Inhibiting Activity Following mRNA Vaccination

Transplant Infectious Disease, EarlyView.
Kidney transplant recipients develop nasal mucosal antibodies after systemic COVID‐19 vaccination, which are able to inhibit binding of SARS‐CoV‐2 to the ACE2 receptor, but at a lower concentration than the general population. ABSTRACT Background Less than 60% of kidney transplant recipients (KTRs) become IgG seropositive for the viral spike (S ...

CFD Simulation of the Interaction Between a Macrobubble and a Dilute Dispersion of Oil Droplets in Quiescent Water

Clean Technologies
Wastewater generation is a growing concern in the preliminary treatment of heavy crude oil and tar sand. The separation of fine oil droplets from water by flotation is a critical process in the production of bitumen from tar sand. The flow structure from

3D numerical analysis of a dam - break using VOF method and LES turbulence model

Ingeniería del Agua, 2018
In this paper, three-dimensional numerical analysis of dam-break flow pattern in a laboratory-scale is reported. The simulation was performed using the open source computational fluid dynamics (CFD) solver based on finite volume method (FVM) – OpenFOAM ...

Numerical simulation of bubble generation in a T-junction [PDF]

, 2012
We present a numerical study of the formation of mini-bubbles in a 2D T-junction by means of the fluid dynamics numerical code JADIM. Numerical simulations were carried out for different flow conditions, giving rise to results on the behavior of bubble ...

Mass Transport of a Two Phase Flow Through a Converging Gap With One Moving Wall

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Mechanical seals are designed to separate two fluid phases from each other, exemplified by the separation of ambient air and hydraulic oil in hydraulic cylinder applications. These seals necessarily include a converging gap, even at a microscopic level.

Experiment–simulation synergy on multiscale breakup dynamics in wire arc spray atomization

Advanced Modeling and Simulation in Engineering Sciences
This study investigates Wire Arc Spraying Atomization (WASA) of Ag925 powders through experiments and computational fluid dynamics simulations. Two frameworks were evaluated: a conventional Discrete Phase Model (DPM) and a hybrid Volume-of-Fluid–Discrete
