英文摘要	Direct numerical simulation on the turbulent flow between two parallel walls under constant heat flux reveals that, adding neutrally buoyant finite-size particles at volume fractions of 0.1 and 0.3 and vebulk Reynolds numbers of 3800 and 5600 in general reduces the Nusselt number on average but enhances it near the walls. The enhancement is contributed by the near-wall streamwise vortex intensification, which is more significant for spheres than for prolates and oblates. These findings are helpful to intensify the wall-to-liquid heat transfer in particle-laden turbulent flow.
