KW - Diffuse-interface lattice Boltzmann method, particulate flows, convergence rate.
AB - <p style="text-align: justify;">In this paper, an improved diffuse-interface lattice Boltzmann method for
particulate flows is developed. In this method, the difference in viscosity between
the fluid and the particle is considered, and a smooth function is introduced to the
collision term of the evolution equation. Some simulations are performed to test the
method, and the numerical results show that, compared to the previous diffusion-interface lattice Boltzmann method [J. Liu et al., Comput. Fluids 233 (2022) 105240]
which only has a first-order accuracy in space, the present one has a second-order
convergence rate in space.</p>
