摘　　要：为了研究含有内肋的平板通道的强化传热性能,文中建立了3种不同形状的内肋几何模型,采用CFD技术对以水为流体的平板通道内的强化传热性能进行了数值模拟,获得3种模型在层流并且定雷诺数条件下的速度场、压力场及温度场,基于场协同原理对其速度与温度梯度的协同效果和速度与压降梯度的协同效果进行分析和比较。通过分析综合传热性能增强因子获得强化换热情况最佳的内肋平板通道模型,为平板通道工程应用中的节能优化设计提供参考依据。In order to study the heat transfer enhancement performance of flat plate channels with inner ribs, three different geometric models of the inner ribs had been established.The numerical simulation of the heat transfer enhancement in flat plate channels with water as fluid had been carried out by using CFD techniques.The velocity field,pressure field and temperature field of three models had been obtained at the condition of laminar flow and constant Reynolds number.Based on the principle of field synergy, the synergistic effect of velocity and temperature gradient and the synergistic effect of velocity and pressure gradient were analyzed and compared.
