An Immersed Boundary Method for Two-fluid Mixtures. [PDF]
J Comput Phys, 2014 We present an Immersed Boundary method for interactions between elastic boundaries and mixtures of two fluids. Each fluid has its own velocity field and volume-fraction. A penalty method is used to enforce the condition that both fluids' velocities agree with that of the elastic boundaries.

A Non-Equilibrium Interpolation Scheme for IB-LBM Optimized by Approximate Force
Axioms, 2023 A non-equilibrium scheme and an optimized approximate force are proposed for the immersed boundary–lattice Boltzmann method (IB-LBM) to solve the fluid–structure interaction (FSI) equations.

Parametric Resonance in Immersed Elastic Boundaries
SIAM Journal on Applied Mathematics, 2004 Summary: We investigate the stability of a fluid-structure interaction problem in which a flexible elastic membrane immersed in a fluid is excited via periodic variations in the elastic stiffness parameter. This model can be viewed as a prototype for active biological tissues such as the basilar membrane in the inner ear, or heart muscle fibers ...

An immersed boundary method for rigid bodies [PDF]
Communications in Applied Mathematics and Computational Science, 2016 We develop an immersed boundary (IB) method for modeling flows around fixed or moving rigid bodies that is suitable for a broad range of Reynolds numbers, including steady Stokes flow. The spatio-temporal discretization of the fluid equations is based on a standard staggered-grid approach.

On the effect of the contact surface definition in the Cartesian grid finite element method
Advanced Modeling and Simulation in Engineering Sciences, 2018 The definition of the surface plays an important role in the solution of contact problems, as the evaluation of the contact force is based on the measure of the gap between the solids.

A Multi-Fidelity Framework for Wildland Fire Behavior Simulations over Complex Terrain
Atmosphere, 2021 A method for the large-eddy simulation (LES) of wildfire spread over complex terrain is presented. In this scheme, a cut-cell immersed boundary method (CC-IBM) is used to render the complex terrain, defined by a tessellation, on a rectilinear Cartesian ...
