Based on the study of isothermal inert particle sedimentation, the Arbitrary Lagrangian-Eulerian technique was used to solve the problem of sedimentation of two solid particles with thermal convection, including the energy equation. The results show that because of the dynamic wake caused by thermal convection, the trajectory of particles are distinct from each other when settling in isothermal, cool and hot fluid; there is vortex shedding in hot fluid, while in cool fluid a strong upward thermal plume forms.
