Realistic simulation of multi-scale fluid-solid coupling

2008 9th International Conference on Computer-Aided Industrial Design and Conceptual Design, 2008
In this paper, we present a novel method for simulating middle- and small-scale details of incompressible viscous fluids and solid coupling. To animate the fluid model, we use the Smoothed Particle Hydrodynamics (SPH) method, which models the flow as a particle system in middle-scale, and based on it, we focus on the interaction between water and solid

Partitioned Fluid–Solid Coupling for Cardiovascular Blood Flow

Annals of Biomedical Engineering, 2010
We present a 3D code-coupling approach which has been specialized towards cardiovascular blood flow. For the first time, the prescribed geometry movement of the cardiovascular flow model KaHMo (Karlsruhe Heart Model) has been replaced by a myocardial composite model.

A coupled fluid–solid model for problems in geomechanics: Application to sand production

International Journal for Numerical and Analytical Methods in Geomechanics, 2011
AbstractSome of the most challenging problems in geomechanics involve the coupling between fluid flow and solid deformation. In this paper we briefly present an overview of existing coupling methods to problems involving fluid flow and deformation and describe testing of a new discrete‐based coupling method for problems in porous media.

LATIN strategy for coupled fluid-solid problems in the domain

2001
A new computational strategy based on the Large Time INcrement (LATIN) approach is used to solve coupled problems in multiphysics. It is applied to the consolidation of porous saturated soil and then compared with another computational strategy.

Thermal-Fluid-Solid Coupling in Thermal Characteristics Analysis of Rolling Bearing System Under Oil Lubrication

, 2020
It is necessary to use the thermal network method for thermal analysis of the bearing, but there are still some shortcomings. In this paper, a novel thermal network model of the bearing transient temperature is developed considering the thermal-fluid ...

A canonical problem for fluid-solid interfacial wave coupling

Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1996
The author studies a two-dimensional problem which describes the wave propagation in a system consisting of a semi-infinite rigid strip inserted between two half-spaces, one being solid and the other being liquid. The strip is smoothly bonded to the solid half-space which is characterized by its Lamé constants.

The numerical analysis of fluid-solid interactions for blood flow in arterial structures Part 2: Development of coupled fluid-solid algorithms

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1998
In this paper, the authors extend their study of wall mechanics given in Part 1 to the overall problem of fluid-solid interactions in arterial flows. Fluid-solid coupling has become a specific topic in computational methods and applied mechanics. In this review, firstly, the effects of elasticity of blood vessels on wave propagation and local flow ...
