A Coupled Lattice Boltzmann Method and Discrete Element Method for Discrete Particle Simulations of Particulate Flows
Discrete particle simulations are widely used to study large–scale particulate flows in complex geometries where particle–particle and particle–fluid interactions require an adequate representation but the computational cost has to be kept low. In this work, we present a novel coupling approach for such simulations. A lattice Boltzmann formulation of the generalized Navier–Stokes equations is u...
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 کاملImplicit velocity correction-based immersed boundary-lattice Boltzmann method and its applications
A version of immersed boundary-lattice Boltzmann method (IB-LBM) is proposed in this work. It is based on the lattice Boltzmann equation with external forcing term proposed by Guo et al. [Z. Guo, C. Zheng, B. Shi, Discrete lattice effects on the forcing term in the lattice Boltzmann method, Phys. Rev. E 65 (2002) 046308], which can well consider the effect of external force to the momentum and ...
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 کاملA lattice Boltzmann based implicit immersed boundary method for fluid-structure interaction
The immersed boundary method is a practical and effective method for fluid–structure interaction problems. It has been applied to a variety of problems. Most of the timestepping schemes used in the method are explicit, which suffer a drawback in terms of stability and restriction on the time step. We propose a lattice Boltzmann based implicit immersed boundary method where the immersed boundary...
