Thermal particulate flows are frequently encountered in a wide range of natural and industrial systems such as mechanical and chemical engineering, heat exchangers, and life science [1]. In the present study, direct numerical simulations of spherical particles moving within a turbulent pipe flow have been carried out, while particles experience heat exchange with the surrounding fluid. The present contribution looks into the effect of different thermal conditions on the behavior of particle motion by using a lattice Boltzmann model (LBM) combined with a direct-forcing and direct-heating immersed boundary method (IBM, [2]). All simulations are carried out using the extensively validated in-house solver ALBORZ [3].
