A 3D flexible blood cell model based on immersed boundary lattice Boltzmann method
In order to simulate the hydrodynamics of haemocytes in blood flow more efficiently,a 3D numerical spherical vesicle including a flexible membrane with enclosed plasma is proposed.In the present work,the fluid motion is solved by the Lattice Boltzmann method,and the cell membrane is modeled with the immersed boundary method.A special quadrilateral mesh deriving from a cube is introduced to construct the vesicle surface,such mesh makes it is feasible to employ the Euler- Bernoulli beam theory to obtain the bending force of each grid point,in which the angle calculation is not required.The numerical experiments exhibit that our model can simulate the flexible spherical blood cells getting through a stenotic capillary successfully,and also can actualize the tank-treading motion of a biconcave red blood cell (RBC) in a shear flow.These results indicate that the proposed model is potential to perform a much simpler and more efficient 3D haemocyte simulation.
