Large-eddy simulation of flows past a flapping airfoil using immersed boundary method [PDF]
The numerical simulation of flows past flapping foils at moderate Reynolds numbers presents two challenges to computational fluid dynamics: turbulent flows and moving boundaries. The direct forcing immersed boundary (IB) method has been devel- oped

As an extension of the immersed boundary method with unified interpolation stencil (Kor, Badri Ghomizad, and Fukagata, J. Fluid Sci. Technol., Vol. 12, 2017, JFST0011), we propose an immersed boundary method that can handle moving boundary problems with ...

The immersed boundary method [PDF]
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 ...

The calibration of fluid-object interaction in immersed boundary method
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 ...

Numerical Modeling of Sperm Swimming
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
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.

Simulations of the Whirling Instability by the Immersed Boundary Method [PDF]
Summary: When an elastic filament spins in a viscous incompressible fluid it may undergo a whirling instability, as studied asymptotically by \textit{C. W. Wolgemuth, T. R. Powers}, and \textit{R. E. Goldstein} [Phys. Rev. Lett. 84, 16--23 (2000)]. We use the immersed boundary (IB) method to study the interaction between the elastic filament and the ...

Immersed Boundary-Finite Difference Lattice Boltzmann Method for Liquid-Solid Two-Phase Flows
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.
