Effects of Multistage Geotechnical Erosion on Dynamic Mechanical Response of Buried Pipelines
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.River‐spanning pipelines are prone to serious hazards during flooding events, which can trigger erosion, exposure, and large‐scale flotation. In this research, a numerical simulation framework was developed using smoothed particle hydrodynamics (SPH) to analyze the dynamic behavior of pipelines subjected to dam‐breach flood scenarios.

CFD‐Assisted Spray Decontamination Process Assessment for Nuclear Tank Decommissioning
Science and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.The decontamination of high‐level radioactive nuclear storage tanks with complex internal devices poses critical challenges in nuclear decommissioning engineering. This study develops a computational fluid dynamics (CFD) framework integrating the volume of fluid–discrete phase model (VOF–DPM) with the Eulerian wall film model (EWFM) to systematically ...

Numerical simulation of flows around a finite-length cylinder with free surface
Zhongguo Jianchuan Yanjiu, 2022 ObjectivesIn order to explore the influence of the free surface and free end on the flow field around typical bluff bodies, the flow field around a finite-length cylinder with a free surface is studied. MethodsBased on the delay detached-eddy simulation (

Extrapolation Boundary Conditions for 2‐D Smoothed Particle Hydrodynamics
International Journal for Numerical Methods in Fluids, Volume 97, Issue 9, Page 1248-1279, September 2025.This paper introduces novel inflow, outflow, and wall boundaries for the WCSPH method. Utilising innovative concepts from finite volume methods, fluid properties of sequential dynamic particles with varying distances to boundaries are extrapolated to ghost and wall particles using first‐order Taylor series expansion.
