| 英文摘要 | The heat transfer in fluid flow through static assemblies of randomly distributed spheroids, including spheres, prolates, and oblates, is investigated using direct numerical simulation (DNS). Constant heat fluxes are imposed at individual particle surface by the Neumann boundary condition for temperature. The superficial Reynolds number (Re) and the solid volume fraction (phi) range from 2.5 to 200, and from 0.1 to 0.3, respectively. The simulation results for spheres and prolates agree well with the DNS data and correlations in literature and new correlations for prolates and oblates are proposed. With these results, the particle shape effect on the average Nusselt number (Nu(avg)) is described more comprehensively: At low phi (e.g., 0.1), the Nu(avg) for prolates and oblates are higher than that of spheres, and as Re increases, the Nu(avg) of oblates gradually catches up that of prolates and becomes comparable at Re approximate to 200. Moreover, oblates attenuate and intensify the heat transfer at low and high Re at high phi, respectively. (C) 2020 Published by Elsevier Ltd. |
