Immersed Boundary-Finite Difference Lattice Boltzmann Method Using Two Relaxation Times
Journal of Fluid Science and Technology, 2013 Immersed boundary-lattice Boltzmann methods (IB-LBM) with the single-relaxation time (SRT) cause non-physical distortion in fluid velocity when the Reynolds number is low, i.e.

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 ...

A Resolved CFD-DEM Approach Based on Immersed Boundary Method
Shanghai Jiaotong Daxue xuebao, 2023 Based on the immersed boundary method, a resolved CFD-DEM algorithm is proposed to tackle fluid-solid interaction problems which widely exist. In the proposed method, the fluid filed is described by the computational fluid dynamics in the Eulerian ...

An Immersed Boundary Model of the Cochlea with Parametric Forcing [PDF]
SIAM Journal on Applied Mathematics, 2015 The cochlea or inner ear has a remarkable ability to amplify sound signals. This is understood to derive at least in part from some active process that magnifies vibrations of the basilar membrane (BM) and the cochlear partition in which it is embedded, to the extent that it overcomes the effect of viscous damping from the surrounding cochlear fluid ...

A three-dimensional immersed boundary method for non-Newtonian fluids
Theoretical 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
