BORONI, G et al. An improved immersed-boundary algorithm for fluid-solid interaction in attice-boltzmann simulations. Lat. Am. appl. res. [online]. 2013, vol.43, n.2, pp.181-187. ISSN 0327-0793.
An improved algorithm combining the features of the lattice-Boltzmann and the immersed-boundary methods is presented. Following previous formulations, the method represents a fluid constrained by flexible boundaries by means of a force term acting on the cells adjacent to the boundary, which in turn is moved by the fluid. The present algorithm introduces a more efficient iteration procedure to calculate the fluid-boundary interaction, which facilitates the implementation and improves performance. The simulations were validated against experimental and analytical data showing good agreement and demonstrating the performance of the method to simulate different kind of fluid-solid interaction
