摘      要：The performance of a single or the collection of microswimmers strongly depends on the hydrodynamic coupling among their constituents and *** present a numerical study for a single and a pair of microswimmers based on lattice Boltzmann method(LBM)*** numerical algorithm consists of two separable *** polynomials provide a discretization of the microswimmers and the lattice Boltzmann method captures the dynamics of the surrounding *** two components couple via an immersed boundary *** present data for a single swimmer system and our data also show the onset of collective effects and,in particular,an overall velocity increment of clusters of swimmers.
