In this paper we detail a fast, fully-coupled, partitioned fluid–structure interaction (FSI) scheme. For the incompressible fluid, new fractional-step algorithms are proposed which make possible the fully implicit, but matrixfree, parallel solution of the entire coupled fluid–solid system. These algorithms include artificial compressibility pressure-poisson solution in conjunction with upwind v...

—This paper describes a framework for animating and controlling articulated bodies in a fluid simulation. We illustrate this approach by simulating an autonomous fish in various situations. Our little animal tries to reach a goal while its movement interacts with the fluid. Several algorithms allow the fish to automatically control its locomotion while taking into account the changing fluid for...

The flow-induced translocation of polymer chains through a microfluidic channel is investigated using particle-based Dissipative Particle Dynamics and modified Langevin Dynamics approaches. Adaptive noslip wall boundary conditions have been implemented to model fluid flow in the microfluidic channel, paying attention to controlling fluid density fluctuations. By varying the magnitude of the ext...

We consider the floating body problem in vertical plane on a large space scale. More precisely, we are interested numerical modeling of freely water such as icebergs or wave energy converters. The fluid-solid interaction is formulated using congested shallow model for fluid and Newton’s second law motion solid. make particular focus transfer between solid since it major interest production. A a...

• A numerical scheme is proposed for the direct simulation of complex solid-liquid-gas three-phase flows. coupled LBM-DEM model ensuring mass conservation proposed. The upward migration bubbles through a brine-filled sediment column successfully simulated at various conditions. Simulation results indicate three different flow regimes: connected finger flow, transition and dispersed bubbly flow....
