recommendations! Published in 2025 at "International Journal for Numerical Methods in Fluids"

DOI: 10.1002/fld.5368

Abstract: In this paper, an implicit scheme that uses the least‐square method to compute the pressure gradient term in the momentum equation, mainly for coupled algorithm was proposed. Accurate computation of the pressure gradient is crucial… read more here.

DOI: 10.1080/15376494.2023.2301507

Abstract: Abstract Inspired by tree fractals, a novel square gradient hierarchical multicellular tube (SGHMT) is proposed, and a finite element (FE) model of the structure is constructed using Abaqus/Explicit. The accuracy of the FE numerical model… read more here.

DOI: 10.1080/15376494.2024.2385021

Abstract: Abstract A new type of bi-double square gradient hierarchical tube (DSGHT) is proposed, and its crashworthiness under consistent wall thickness is analyzed. The results show that the energy absorption (EA), specific energy absorption (SEA), and… read more here.

DOI: 10.1103/physreve.100.022803

Abstract: In a recent article, we described how the microscopic structure of density-density correlations in the fluid interfacial region, for systems with short-ranged forces, can be understood by considering the resonances of the local structure factor… read more here.
