Simulating Particle Deposition with the Coarsening Immersed Boundary Lattice Boltzmann Method
Résumé
The mitigation of particle deposition is of great interest for industrial applications. To understand the dynamics of particle sedimentation in the flow, we mainly use the Eulerian-Lagrangian method. However, this method has several drawbacks, such as difficulty in handling complex particle geometries and requiring high computational power. We propose a coarsened immersed boundary lattice Boltzmann method, which is capable of handling complex immersed objects using optimal computing power. The results from coarsening model show very good agreement with results obtained without coarsening.
