Fluid-Particle Interaction with the Immersed Boundary Lattice Boltzmann Method
نویسندگان
چکیده
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 the Chair of System Simulation at the Friedrich-AlexanderUniversität Erlangen-Nürnberg. The immersed boundary method is compared with the momentum exchange method in terms of their ability to reproduce accurate boundary conditions between uid and particles and to provide the correct force interaction at Reynolds numbers Re<10. The purpose of this Master thesis is to present a basic implementation of the immersed boundary method alongside with an analysis of the key factors necessary to ensure the accuracy of the algorithm as a base for large scale simulations of particulate ows.

Numerical Simulation of Fluid Flow over a Ceramic Nanoparticle in Drug Delivery System
In this work, for better understanding of drug delivery systems, blood flow over a ceramic nanoparticle is investigated through microvessels. Drug is considered as a nanoparticle coated with the rigid ceramic. Due to the low characteristic size in the microvessel, the fluid flow is not continuum and the no-slip boundary condition cannot be applied. To solve this problem lattice Boltzmann method...

In this paper, implementation of an extended form of a no-slip wall boundary condition is presented for the three-dimensional (3-D) lattice Boltzmann method (LBM) for solving the incompressible fluid flows with complex geometries. The boundary condition is based on the off-lattice scheme with a polynomial interpolation which is used to reconstruct the curved or irregular wall boundary on the ne...

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...
متن کاملModelling of the Dynamics of an immersed body in a microchannel with stenosis using the immersed boundary method
In the present study, the combination of lattice Boltzmann and immersed boundary methods is used to simulate the motion and deformation of a flexible body. Deformation of the body is studied in microchannel with stenosis and the effect of the flexibility changes on its deformation is investigated. The obtained results in the present manuscript show that by increasing the elasticity modulus, the...
