▎ 摘  要

A modified boundary condition for the distribution function in the Lattice Boltzmann method at the interface between solid and fluid that takes into account a finite mass ratio between two phases and an inelastic reflection is proposed. The new boundary condition is built into the immersed boundary method to compute the interaction between graphene and laminar flow. Numerical simulations are carried out at a Reynolds number of 40, and drag and lift acting on the graphene and its deformation are examined by changing the mass ratio and the coefficient of restitution. It is found that the amplitude of the oscillating motion of the graphene is enhanced when compared with the case of infinite mass ratio with perfect collision.
