Multiple red blood cell (RBC) flows through a symmetric microvascular bifurcation model have been simulated with the two-dimensional immersed-boundary lattice-Boltzmann method. The cell free layer (CFL), the RBC separation process and trajectories, and the resulting hematocrit distributions in the daughter branches have been examined, and the effects of(More)
In this study, we simulated multiple red blood cells flowing through straight microvessels with the immersed-boundary lattice-Boltzmann model to examine the shear stress variation on the microvessel surface and its relation to the properties of cell-free layer. Significant variation in shear stress has been observed due to the irregular configuration of(More)
Mass conservation and momentum transfer across solid-fluid boundaries have been active topics through the development of the lattice-Boltzmann method. In this paper, we review typical treatments to prevent net mass transfer across solid-fluid boundaries in the lattice-Boltzmann method, and argue that such efforts are in general not necessary and could lead(More)
Microscopic flow-fiber interaction is frequently encountered in biofluid systems. In this paper, we propose a three-dimensional numerical model for such systems, including a spring network model for the elastic fiber, the lattice Boltzmann method for the fluid flow, and the immersed boundary method for the flow-structure interaction. Simulations are also(More)
