项目摘要
Development of a rapid immersion cooling technique is very important as a basis of the production of fibers of a new class of high performance materials, such as amorphous alloys, nanocrystalline alloys etc., by melt spinning process. Also, understanding of the mechanism of the incipience of solid-liquid contact during the immersion cooling process is very important because it is closely connected with the vapor explosion phenomena. In this study, experiments were conducted to investigate the fluid flow and heat transfer characteristics during the rapid quenching of thin horizontal platinum wires (0.3 and 0.5 mm in diameter) in a pool of subcooled liquids (water, CaCl_2/water solution and ethanol). The falling speed of the test wire ranged from 0.1 to 1.5m/s, the subcooling of quenching liquid from 20 to 80K,and the concentration of CaCl_2 from 0 to 40%. For water and CaCl_2/water solution, the solid-liquid contact during the quenching process was measured using a kind of conductance p … More robe. The results are summarized as follows : (1) The transient boiling curve obtained from the cooling curve has two minimum-heat-flux points. (2) At a wall temperature higher than the upper minimum-heat flux point(named the M1 point), the wire is covered with vapor film and the occurrence of solid-liquid contact is very rare. When the wall superheat decreases below the M1 point, both the solid-liquid signal and the heat flux increase rapidly. (3) In the region of wall superheat exceeding the lower minimun-heat-flux point (named the M2 point) , the wall superheat at the M1 point and the heat flux increases with increasing liquid subcooling, falling velocity and CaCl_2 concentration. (4) The wall superheat at the M2 point is constant irrespective of the liquid subcooling and falling velocity. It increases with increasing CaCl_2 concentration. (5) In the region of wall superheat important for the production of amorphous alloys, the average heat flux increases as much as 140% by use of the CaCl_2 solution. The mechanism of solid-liquid contact was studied theoretically from the viewpoint of hydrodynamic stability of thin vapor film formed on the wire surface. The theory considered the linear stability of disturbance superimposed on the vapor film. The motion was assumed to be governed by the wave equation on the liquid side and by the laminar flow equation on the vapor side. The theoretical prediction of the heat transfer coefficient at the neutral stability point compared well with that at the M1 point for water and ethanol. Less
快速浸没冷却技术的发展是熔体纺丝法生产非晶合金、纳米晶合金等新型高性能材料纤维的重要基础。此外,了解浸没冷却过程中固液接触发生的机理也非常重要,因为它与蒸汽爆炸现象密切相关。本文研究了直径为0.3 mm和0.5 mm的细水平铂丝在过冷液体(水、CaCl_2/水溶液和乙醇)池中快速淬火时的流体流动和传热特性。试验线材下落速度为0.1 ~ 1.5m/s,淬火液过冷度为20 ~ 80K, CaCl_2浓度为0 ~ 40%。对于水和CaCl_2/水溶液,采用一种电导法测量了淬火过程中的固液接触。结果表明:(1)由冷却曲线得到的瞬态沸腾曲线有两个最小热通量点。(2)在壁面温度高于上部最低热通量点(称为M1点)时,线材被汽膜覆盖,固液接触的发生非常罕见。当壁面过热度降到M1点以下时,固液信号和热流密度均迅速增大。(3)在壁面过热度超过下最小热流点(M2点)的区域,M1点壁面过热度和热流密度随液体过冷度、下降速度和CaCl_2浓度的增加而增大。(4)无论液体过冷度和下降速度如何,M2点的壁面过热度都是恒定的。它随CaCl_2浓度的增加而增大。(5)在非晶合金生产中重要的壁面过热区,CaCl_2溶液的平均热流密度可提高140%。从金属丝表面形成的气膜流体动力稳定性的角度,对固液接触机理进行了理论研究。该理论考虑了叠加在气膜上的扰动的线性稳定性。该运动假定由液体侧的波动方程和蒸汽侧的层流方程控制。对水和乙醇在中性稳定点的换热系数的理论预测与在M1点的换热系数的理论预测比较好。少
