摘要: In this work, the field (continuity, momentum and thermal energy) equations togetherwith a cell model have been solved numerically to elucidate influence of non-Newtonian (Power law rheology) liquid characteristics on liquid-solid heat transfer in packed fluidised beds spherical particles. The results presented herein relate wide ranges conditions bed voidage, power-law index Peclet number but are limited low Reynolds (≤1) flow conditions. Within range conditions, effect is found be small also consistent with available experimental mass these systems.
