Summary

Computational Fluid Dynamics (CFD) and Smoothed Particle Hydrodynamics (SPH) have become core engines for revealing complex flow physics in engineering and natural systems. Their complementary strengths mesh-based fidelity and mesh-free flexibility enable robust simulation of free surfaces, fluid–structure and fluid–soil interaction, multiphase and granular media, large deformations, porous-media transport, and phase change that are difficult to capture experimentally.


This Special Issue gathers recent advances, innovative algorithms, and application-driven studies that push the frontiers of accuracy, stability, efficiency, and reproducibility in CFD/SPH. We especially welcome contributions that connect methods to impactful applications across aerospace, energy systems, porous media and heat/mass transfer, environmental/coastal flows, bio-fluids, and industrial processes, including works that leverage high-performance/GPU computing and data-driven or AI-assisted modelling for acceleration, calibration, and uncertainty quantification.


Potential topics include, but are not limited to:
· Advances in SPH formulations and coupling techniques; hybrid CFD–SPH schemes
· Alternative meshless methods and comparisons/benchmarks
· Multiphysics/multiscale modeling; porous media and phase change
· Numerical stability, accuracy, efficiency, and V&V/UQ practices
· Free-surface, multiphase, and granular flow applications
· Fluid–structure and fluid–soil interaction modeling
· Heat and fluid flow, MHD, and coupled heat–mass transfer
· High-performance/GPU implementations; reduced-order and AI/ML-assisted CFD/SPH

    A Fully Lagrangian Mesh-Free Framework for Fluid–Structure Interaction Based on WC-MPS and Hybrid TL–UL Formulations

    Saeed Tavakoli, Ahmad Shakibaeinia, Najib Bouaanani
    CMES-Computer Modeling in Engineering & Sciences, Vol.147, No.3, 2026, DOI:10.32604/cmes.2026.081925

    Abstract Fluid–structure interaction (FSI) plays a critical role in civil engineering applications, directly influencing structural safety, resilience, and performance. However, the inherent multiphysics complexity of FSI problems presents significant challenges for numerical modeling, particularly under highly dynamic flow conditions. This study presents a fully Lagrangian mesh-free framework for FSI based on the moving particle semi-implicit (MPS) method. The approach couples an enhanced weakly compressible MPS (WC-MPS) fluid solver with a hybrid total–updated Lagrangian (TL–UL) MPS formulation for elastic solids. In the solid phase, strains are evaluated in the reference configuration, while momentum balance is enforced in… More >

    Numerical Simulations of Extreme Deformation Problems in Granular-Dominated Hazard from Indoor to Engineering Geological Scale: A Comparative Study

    Yuxin Tian, Wangxin Yu, Wanqing Yuan, Qingquan Liu, Xiaoliang Wang
    CMES-Computer Modeling in Engineering & Sciences, Vol.146, No.3, 2026, DOI:10.32604/cmes.2026.078776
    (This article belongs to the Special Issue: Recent Developments in SPH and CFD Methods for Complex Flow Simulations)
    Abstract Granular flow, such as hopper discharge and debris flows, involves complex multi-scale, multi-phase, and multi-physics coupling, posing significant challenges for numerical simulation. Over the past two decades, methods like the Discrete Element Method (DEM), Smoothed Particle Hydrodynamics (SPH), and Depth-Averaging Method (DAM), have been developed to address these problems. However, their applicability across different scales remains unclear due to differences in physical assumptions and numerical algorithms. Therefore, a comprehensive evaluation is critically needed. This study selects three typical methods (DEM, SPH, and DAM) to examine their convergence behavior, boundary condition implementation, and limitations in physical More >
