A novel fluid–solid coupling model for the oil–water flow in the natural fractured reservoirs

, 2021
The mutual coupling effect between the fluid flow and the in situ stress fields cannot be ignored during the development of natural fractured reservoirs (NFRs), such as in the waterflooding process. In this study, a discrete fracture model is proposed to

Fluid-solid coupling response of shield tunnel lining structure under high water pressure

Marine georesources & geotechnology, 2021
When a river-crossing shield tunnel is excavated in water-rich soft clay strata, the mechanical properties of the segment lining structure are significantly affected by the water pressure and fluid-solid coupling, especially when the water level changes ...

Research on Propeller Modeling and Fluid-Solid Coupling Analysis

Marine Technology Society Journal, 2021
Abstract Taking the AU5-50 propeller as an example, the detailed process of propeller modeling with atlas method and PropCad is compared. By comparing the auxiliary profiles used for modeling, it is pointed out that the blade model established by PropCad has more complete features and is not restricted by the propeller type.

Particle-Based Simulation of Fluid-Solid Coupling

2013
We present an efficient framework for fluid-solid coupling, including both rigid and elastic bodies. Based on a unified particle model, we apply different coupling scheme for fluid-solid and solid-solid coupling respectively. Realistic and versatility are achieved by coupling all the objects adaptively. With the help of GPU accelerating, we gain a real-

A fluid–solid coupling model for hydraulic fracture of deep coal seam based on finite element method

The Physics of Fluids
The fluid–solid coupling effect is more pronounced in the process of deep coal seam development compared to shallow coalbed methane, exerting a greater influence on production, and cannot be disregarded. Throughout the extraction process, the interaction

Stable and Fast Fluid–Solid Coupling for Incompressible SPH

Computer Graphics Forum, 2014
AbstractThe solid boundary handling has been a research focus in physically based fluid animation. In this paper, we propose a novel stable and fast particle method to couple predictive–corrective incompressible smoothed particle hydrodynamics and geometric lattice shape matching (LSM), which animates the visually realistic interaction of fluids and ...

Coupled Fluid/Solid Heat Transfer Computation for Turbine Discs

Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2001
This paper considers the coupling of a finite element thermal conduction solver with a steady, finite volume fluid flow solver. Two methods were considered for passing boundary conditions between the two codes — transfer of metal temperatures and either convective heat fluxes or heat transfer coefficients and air temperatures.
