Comparison of the interpolated bounce-back and immersed boundary methods in LBE for laminar flow around a cylinder.

Abstract:  Both the bounce-back scheme with second-order spatial interpolations and immersed boundary methed (IBM) are simple schemes for curved and complex boundaries in the lattice Boltzmann equation. Detailed evaluation of these two schemes are carried out in this paper using the benchmark compution of laminar ow around a cylinder. We found that the bounce-back scheme with second-order spatial interpolation is better than immersed boundary method in accuracy and efficiency.
