Abstract: This work is devoted to study numerical methods for multiphase flow simulation and implementation of boundary conditions on solid surface for solid-multiphase flow interactions. In respect of multiphase flow simulation, a stencil adaptive-phase field-Lattice Boltzmann Method (LBM) is developed. It enables a high resolution of interfacial dynamics with great grid distribution flexibility. Additionally, a phase field-LBM for simulation of multiphase flow with density contrast is also developed. On the other hand, we take the first endeavour to develop an immersed Boundary method (IBM) for Neumann boundary conditions on solid surface in this work. It releases IBM from the restrictions and opens the possibility of IBM simulation for ubiquitous fluid-solid interactions involving Neumann boundary conditions. Last but not least, application of immersed boundary-phase field-LBM for simulation of solid-multiphase flow interactions is also demonstrated.
