摘要

探讨了超临界压力下煤油流过内径为 1.70mm的不锈钢管的传热特性 .实验在压力为 5、 15MPa

质量流率为 85 0 0～ 5 10 0 0kg·m-2 ·s-1和热负荷高达 5 5 .0MW·m-2 的参数范围内进行 .结果表明 :在内壁温达到拟临界温度时有拟沸腾现象发生 ;进一步提高热负荷会发生传热恶化

加入添加剂能提高临界热负荷 ;在极高热负荷下还会发生第 2次传热强化

限制了传热恶化的壁温飞升 .给出了煤油的强制对流传热关联式

计算值和实验值吻合良好 .

Abstract

Experimental results on heat transfer characteristics of kerosene at supercritical pressure flowing inside a stainless-steel tube with an internal diameter of 1.70 mm are discussed in this paper. The tests are conducted at pressures of 5

15 MPa

mass velocities of 8500-51000 kg·m -2 ·s -1

and heat fluxes up to 55 MW·m -2 . Enhancement of heat transfer due to pseudo-boiling is found when wall temperature reaches pseudocritical temperature. Deterioration of heat transfer occurs with wall heat flux increasing. The critical heat flux increases when an additive is added into kerosene. At a very high heat flux secondary enhancement of heat transfer occurs

which could limit the deterioration of heat transfer. A turbulent heat transfer correlation for this kind of heat transfer which fits the data well is given.
