| Research Abstract |
A new numerical method for solid-liquid two-phase flow based on the lattice Boltzmann method is developed, and applied to the motion of a deformable body in microscale complicated geometries. By extending our previous work, we investigate the behavior of a non-spherical body, e.g., a biconcave body such as a red blood cell in viscous fluid. Also, we simulate the motion of a viscoelastic body in complex channels with a constriction. From these results, it is found that the validity of the present method is demonstrated, and it can be a promising numerical method as commercial software in the future.
