从一般控制方程出发

根据环管热进口段传热特点

结合优化选择影响传热的诸如速度分布、湍流热量扩散率和动量扩散率等半经验关系式

建立能借助计算机理论求解的计算模型

并在进一步简化条件下计算、分析了轴向导热对进口段传热的影响。

On the ground of general control equations

by paying attention to heat transfer characteristics in thermal entrance region and optimizing relations which affect the heat transfer

such as ones for velocity fields

eddy diffusivities for heat and momentum transfer

the present authors established a calculation model easy to be solved with the help of computer program. With the further simplified conditions

the effect of an axial heat conduction on heat transfer to liquid sodium in thermal entrance region was calculted and analyzed.
