Dynamic Behaviours of a Filament in a Viscoelastic Uniform Flow
Fluids, 2021 The dynamic behaviours of a filament in a viscoelastic uniform flow were investigated by an immersed boundary-lattice Boltzmann method. The effects of the Reynolds numbers (Re, ranging from 10 to 200) and the Weissenberg number (Wi, ranging from 0 to 1.2)

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.

The volume-filtering immersed boundary method
Journal of Computational Physics, 2023 We present a novel framework to deal with static and moving immersed boundaries (IB). In this strategy, called Volume-Filtering Immersed Boundary (VFIB) method, transport equations are derived by filtering the Navier-Stokes equations and accounting for stresses at the solid-fluid interface.

The calibration of fluid-object interaction in immersed boundary method
EPJ Web of Conferences, 2017 In modelling of elastic objects immersed in a fluid, very important part of the model is the interaction between objects and fluid. In models based on immersed boundary method and lattice-Boltzmann method, this interaction is mediated by friction ...

Radial basis function (RBF)-based interpolation and spreading for the immersed boundary method [PDF]
, 2014 Immersed boundary methods are efficient tools of growing interest as they allow to use generic CFD codes to deal with complex, moving and deformable geometries, for a reasonable computational cost compared to classical body-conformal or unstructured mesh

Numerical Modeling of Sperm Swimming
Fluids, 2021 Due to rising human infertility, sperm motility has been an important subject. Among the hundreds of millions of sperms on the journey up the oviducts, only a few excellent travelers will reach the eggs.

Immersed Boundary Method Using Ghost Cells in a Three-Dimensional Case
Современные информационные технологии и IT-образование, 2020 When solving numerically gas dynamics problems, one often encounters difficulties in processing regions with complex geometry. Generating consistent computational grids for such areas may be a complex task.

The immersed boundary method [PDF]
Acta Numerica, 2002 This paper is concerned with the mathematical structure of the immersed boundary (IB) method, which is intended for the computer simulation of fluid–structure interaction, especially in biological fluid dynamics. The IB formulation of such problems, derived here from the principle of least action, involves both Eulerian and Lagrangian variables ...

Immersed Boundary-Finite Difference Lattice Boltzmann Method for Liquid-Solid Two-Phase Flows
Journal of Fluid Science and Technology, 2011 An immersed boundary method based on a finite difference lattice Boltzmann method (IB-FDLBM) is presented. The FDLBM solves the discrete Boltzmann equation including an additional collision term by using finite difference schemes.
