Er/Sc Co‐Doping Enabling Laser‐Powder Bed Fusion Aluminum Alloys With Superior Strength and Uncompromised Toughness

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐strength aluminum (Al) alloys are usually unprintable by laser powder bed fusion (LPBF) due to the severe hot cracking along the columnar grains. Doping elements scandium (Sc) and/or zirconium (Zr) is an effective way to eliminate hot cracks by refining the grain size to nearly nanoscale levels.

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

Transplant Infectious Disease, Volume 28, Issue 4, July/August 2026.
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 ...

Application of CLEAR-VOF method to wave and flow simulations

Water Science and Engineering, 2012
A two-dimensional numerical model based on the Navier-Stokes equations and computational Lagrangian-Eulerian advection remap-volume of fluid (CLEAR-VOF) method was developed to simulate wave and flow problems. The Navier-Stokes equations were discretized

Jet Flow Field Analysis of Convergent‐Divergent Nozzle for Hydraulic Perforation for Natural Gas Hydrates

Energy Science &Engineering, Volume 14, Issue 6, Page 3042-3055, June 2026.
Combining the nozzle structure and wellbore size of the second natural gas hydrate trial production, the CFD is employed to analyze the internal and external flow fields of convergent–divergent cavitation nozzle. Analyzing the influence of various structural parameters of the nozzle on its jet performance, and the nozzle configuration with optimal jet ...

A Finite Element Method for Compressible and Turbulent Multiphase Flow Instabilities with Heat Transfer

Fluids
We present a new finite element framework for modeling compressible, turbulent multiphase flows with heat transfer. For two-fluid systems with a free surface, the Volume of Fluid (VOF) method is implemented without the need for interface reconstruction ...

3D CFD validation of invert trap efficiency for sewer solid management using VOF model

Water Science and Engineering, 2016
Earlier investigators have numerically carried out performance analysis of the invert trap fitted in an open channel using the stochastic discrete phase model (DPM) by assuming the open channel flow to be closed conduit flow under pressure and assuming ...

The CFD Method-Based Research on Damaged Ship’s Flooding Process in Time-Domain

Polish Maritime Research, 2019
The flooding process is one of the main concerns of damaged ship stability. This paper combines the volume of fluid (VOF) method incorporated in the Navier-Stokes (NS) solver with dynamic mesh techniques to simulate the flooding of a damaged ship.

Three dimensional numerical simulations for non-breaking solitary wave interacting with a group of slender vertical cylinders

International Journal of Naval Architecture and Ocean Engineering, 2009
In this paper we validate a numerical model for wave-structure interaction by comparing numerical results with laboratory data. The numerical model is based on the Navier-Stokes (N-S) equations for an incompressible fluid. The N-S equations are solved by
