An immersed boundary lattice Boltzmann approach for microscopic blood flows
In this paper, we develop an immersed boundary lattice Boltzmann approach to simulate deformable capsules in flows. The lattice Boltzmann method is utilized to solve the incompressible flow field over a regular Eulerian grid, while the immersed boundary method is employed to incorporate the fluid–membrane interaction with a Lagrangian representation of the capsule membrane. This algorithm was v...
متن کاملAn immersed boundary-lattice Boltzmann method for single- and multi-component fluid flows
The paper presents a numerical method to simulate singleand multi-component fluid flows around moving/deformable solid boundaries, based on the coupling of Immersed Boundary (IB) and Lattice Boltzmann (LB) methods. The fluid domain is simulated with LB method using the single relaxation time BGK model, in which an interparticle potential model is applied for multi-component fluid flows. The IB-...
متن کاملFluid-Particle Interaction with the Immersed Boundary Lattice Boltzmann Method
The thesis presents an analysis of the continuous forcing approach of the immersed boundary method for the simulation of the interaction between uid and rigid particles in combination with the single relaxation lattice Boltzmann method. The immersed boundary method as a numerical algorithm is implemented in the context of two massively parallel software frameworks (waLBerla and pe) developed at...
متن کاملAn Immersed Boundary-Lattice Boltzmann Method for Swimming Sperms
This work presents an immersed boundary–lattice Boltzmann method for free-swimming sperms in an incompressible viscous fluid. This method involves sperm model, fluid solver and fluid– structure interaction (FSI). The sperm is simplified as a nonlinear beam. To drive the swimming motion, an internal moment is introduced into the beam equation. The fluid dynamics is obtained by solving the lattic...
متن کاملSimulation of three-dimensional flows over moving objects by an improved immersed boundary–lattice Boltzmann method
An improved immersed boundary–lattice Boltzmann method (IB–LBM) developed recently [28] was applied in this work to simulate three-dimensional (3D) flows over moving objects. By enforcing the non-slip boundary condition, the method could avoid any flow penetration to the wall. In the developed IB–LBM solver, the flow field is obtained on the non-uniform mesh by the efficient LBM that is based o...
