Witryna27 sty 2012 · To reduce such a numerical boundary slip, an immerse boundary lattice Boltzmann model based on multiple relaxation times is proposed in this paper. A special formula is given between two relaxation time parameters in the model. A rigorous analysis and the numerical experiments carried out show that the numerical … WitrynaImmersed boundary methods are frequently employed for simulating ows at low Reynolds numbers or for applications where viscous boundary layer e ects can be neglected. The primary shortcoming of Cartesian mesh immersed boundary methods is the inability of e ciently resolving thin turbulent boundary layers in high-Reynolds …
