Lattice Boltzmann Fluid-Structure Interaction
Research Guide
What is Lattice Boltzmann Fluid-Structure Interaction?
Lattice Boltzmann Fluid-Structure Interaction (LBM-FSI) couples Lattice Boltzmann Method solvers with immersed boundary or sharp-interface techniques to simulate fluid flows interacting with deformable or moving solid structures.
LBM-FSI integrates LBM for fluid dynamics with immersed boundary methods (IBM) for handling complex geometries and large deformations. Key applications include elastic filaments, particles in turbulence, and porous media flows. Over 20 papers since 2003 cite foundational works like Feng & Michaelides (2003) with 995 citations.
Why It Matters
LBM-FSI enables simulation of flapping wings and blood flow with deformable membranes, critical for aerodynamics and bioengineering. Feng & Michaelides (2003) established IBM-LBM for fluid-particle interactions, applied in microcirculation studies (Lee et al., 2013). Tian et al. (2011) advanced elastic filament simulations, impacting fish swimming models. Vanella & Balaras (2009) improved embedded-boundary accuracy for large deformations in engineering designs.
Key Research Challenges
Mass conservation in multiphase FSI
Multiphase LBM-FSI struggles with mass leakage at fluid-structure interfaces during large deformations. Liu et al. (2015) highlight inconsistencies in porous media simulations using MRT models. Higher-order IBM formulations are needed for long-term stability.
Higher-order immersed boundary accuracy
Standard IBM spreading and interpolation cause first-order errors in near-wall flows. Tian et al. (2011) report reduced accuracy for elastic filaments at high Reynolds numbers. Moving-least-squares reconstruction by Vanella & Balaras (2009) addresses this but increases computational cost.
Scalability for 3D turbulent FSI
Fully resolved 3D simulations of particles in turbulence demand high resolution. ten Cate et al. (2004) used spectral forcing with LBM but limited to monodisperse spheres. Extension to polydisperse deformable structures remains computationally prohibitive.
