| 摘 要： | 本文对稠密栅元内的湍流流动和传热特性进行了分析。首先利用实验数据对计算结果进行了验证，然后分析了Re和P/D等参数对稠密栅元内的摩擦阻力系数和传热系数的影响。Re和P/D均会对稠密栅元内的流动传热特性产生显著影响，但传统的理论模型无法描述P/D对栅元内的摩擦阻力系数和传热系数的影响。P/D=1.03是一临界点，这种条件下的稠密栅元内的流动和传热是最安全的，也是最高效的。此时核反应堆的功率和系统的传热能力可同时达到最大。

| Abstract: | The turbulent flow and heat transfer in tight lattice were investigated in the paper.The calculation results were firstly validated with experimental data,then the effects of Re and P/D on the frictional resistance and heat transfer coefficients in tight lattice were analyzed.Both the effects of Re and P/D on the flow and heat transfer characteristics in tight lattice are significant.However,the traditional theoretical models can not predict the effects of Re and P/D on the frictional ictional resistance an... |
