Full-Scale Simulation of the Fluid–Particle Interaction Under Magnetic Field Based on IIM–IBM–LBM Coupling Method

In this article, a full-scale computational model for fluid–particle interaction under magnetic field is developed. model, the fluid solved by lattice Boltzmann method, and hydrodynamic force acting on particle computed immersed boundary method . The numerical solutions of in fluid–solid domain are achieved interface with finite difference scheme, which normal tangential jump conditions intensity applied to modify standard scheme. stress tensor along can be calculated accurately. Unlike widely used point–dipole determined integration method. Numerical simulation several tests carried out validate proposed model. results demonstrate validity present Moreover, magnetoviscous effect studied simulating motion elliptical particles uniform shear flow.
