Numerical simulation of the airflow–rivulet interaction associated with the rain-wind induced vibration phenomenon [PDF]
, 2011 Rain-wind induced vibration is an aeroelastic phenomenon that occurs on the inclined cables of cable-stayed bridges. The vibrations are believed to be caused by a complicated nonlinear interaction between rivulets of rain water that run down the cables ...

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.

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.
