Outline of Final Research Achievements |
The lattice Boltzmann method (LBM) for two-phase flows containing a deformable body with a viscoelastic membrane is applied to the motion of a biconcave disk-shaped body (e.g., red blood cell) in a constricted pressure-driven circular pipe flow. Time variations of the deformation index and the axial velocity of the body are calculated in the constricted region. By comparison with the results in a square pipe flow, it is found that the body in the circular pipe flow undergoes a little larger deformation and passes more slowly than in the case of square pipe flow. Next, fluid flows with a circular cylinder in a two-dimensional T-shaped pipe are simulated by the LBM incorporated with an immersed boundary method (called IB-LBM). We investigate the effects of the initial position of the cylinder, the pressure difference between the two outlets, and the ratio of the diameter of the cylinder to the width of the pipe on the behavior of the cylinder.
