Plunge Pool Rock Scour Assessment by Fluid-Solid Coupling
, 2022 This paper presents a novel approach for detailed 2D numerical assessment of rock scour in plunge pools or unlined channels downstream of hydraulic structures. The approach is based on an automated coupling between the 3D hydraulics and the turbulence of an impacting jet (or any other turbulent flow environment) and the detailed bathymetric evolution ...

Superseismic Loading and Shock Polars: An Example of Fluid-Solid Coupling [PDF]
, 2002 We propose a two-dimensional problem involving fluid-solid coupling where a solution is given in closed form. The upper half of the domain is modeled as an isotropic solid; the lower part as a compressible gas.

Fluid-solid Coupling Analysis of Riser based on CFD
Scientific Journal of Technology, 2023 The riser is the only channel connecting the submarine pipeline oil gas and offshore platform structures, offshore oil and gas development and utilization of lifelines, offshore pipeline system is the weakest vulnerable link. Due to its long and thin structure, the marine riser is easy to failure and failure in the complex working conditions.
