We present a new approach for the mechanically consistent modelling and simulation of fluid–structure interactions (FSI) with contact. The fundamental idea consists combining relaxation contact conditions seepage through porous layer co-dimension one during For latter, Darcy model is considered in thin attached to solid boundary limit infinitesimal thickness. resulting computational both simple...

Fluid–structure interactions (FSI) play a crucial role in the design, construction, service and maintenance of many engineering applications, e [...]

We propose a novel method to implicitly two-way couple Eulerian compressible flow to volumetric Lagrangian solids. The method works for both deformable and rigid solids and for arbitrary equations of state. The method exploits the formulation of [11] which solves compressible fluid in a semi-implicit manner, solving for the advection part explicitly and then correcting the intermediate state to...

In this article, we analyze and numerically assess a new fictitious domain method for fluid-structure interactions in two and three dimensions. The distinguishing feature of the proposed method is that it only solves for one velocity field for the whole fluid-structure domain; the interactions remain decoupled until solving the final linear algebraic equations. To achieve this the finite elemen...

We have investigated the structural properties of a fluid in which particles, interacting via soft potentials, are imbibed into a disordered porous structure built up by soft particles. Using a Gaussian potential for all interactions involved, we determine via Monte Carlo simulations and integral-equation theory the fluid-fluid, fluid-matrix, connected, and blocked structure factors. Within the...
