Immersed Boundary Simulations of Active Fluid Droplets. [PDF]

open access: yesPLoS ONE, 2016
We present numerical simulations of active fluid droplets immersed in an external fluid in 2-dimensions using an Immersed Boundary method to simulate the fluid droplet interface as a Lagrangian mesh.

Pressure boundary conditions for immersed-boundary methods. [PDF]

open access: yesJ Comput Phys, 2023
Immersed boundary methods have seen an enormous increase in popularity over the past two decades, especially for problems involving complex moving/deforming boundaries. In most cases, the boundary conditions on the immersed body are enforced via forcing functions in the momentum equations, which in the case of fractional step methods may be problematic

Numerical Modeling Using Immersed Boundary-Lattice Boltzmann Method and Experiments for Particle Manipulation under Standing Surface Acoustic Waves [PDF]

open access: yesMicromachines, 2023
In this work, we employed the Immersed Boundary-Lattice Boltzmann Method (IB-LBM) to simulate the motion of a microparticle in a microchannel under the influence of a standing surface acoustic wave (SSAW).

A three-dimensional immersed boundary method for non-Newtonian fluids [PDF]

open access: yesTheoretical and Applied Mechanics Letters, 2018
: Fluid-structure-interaction (FSI) phenomenon is common in science and engineering. The fluid involved in an FSI problem may be non-Newtonian such as blood. A popular framework for FSI problems is Peskin's immersed boundary (IB) method. However, most of

A high-efficiency discretized immersed boundary method for moving boundaries in incompressible flows [PDF]

open access: yesScientific Reports, 2023
The Immersed Boundary Method (IBM) has an advantage in simulating fluid–structure interaction, owning to its simplicity, intuitiveness, and ease of handling complex object boundaries. The interpolation function plays a vital role in IBM and it is usually

Hybrid finite difference/finite element immersed boundary method. [PDF]

open access: yesInt J Numer Method Biomed Eng, 2017
The immersed boundary method is an approach to fluid-structure interaction that uses a Lagrangian description of the structural deformations, stresses, and forces along with an Eulerian description of the momentum, viscosity, and incompressibility of ...

Multi-GPU Immersed Boundary Method Hemodynamics Simulations. [PDF]

open access: yesJ Comput Sci, 2020
Large-scale simulations of blood flow that resolve the 3D deformation of each comprising cell are increasingly popular owing to algorithmic developments in conjunction with advances in compute capability. Among different approaches for modeling cell-resolved hemodynamics, fluid structure interaction (FSI) algorithms based on the immersed boundary ...

Benchmarking the Immersed Boundary Method for Viscoelastic Flows. [PDF]

open access: yesJ Comput Phys
We present and analyze a series of benchmark tests regarding the application of the immersed boundary (IB) method to viscoelastic flows through and around non-trivial, stationary geometries. The IB method is widely used for the simulation of biological fluid dynamics and other modeling scenarios where a structure is immersed in a fluid. Although the IB
