|Abstract:||A hybrid method is proposed to study the transient deformation of capsules in general and red blood cells in particular under flow. In this method, the immersed boundary concept is introduced into the framework of lattice Boltzmann method, and the multi-block strategy is employed to refine the mesh near the capsule to increase the accuracy and efficiency of computation. A finite element model is employed to obtain the forces acting on the membrane nodes of the three-dimensional red blood cell which is discretized into flat triangular elements. The method was validated by studying the deformation of initially spherical capsules under shear flow. The versatility of the present method was demonstrated by studying the effects of inertia on the deformation of capsules, and the deformation of capsules with complex shape like the biconcave discoid. © 2008 Springer-Verlag.|
