摘要: 国际材料热处理联合会淬火冷却科技委员会(IFHT-TCQ)向各国推荐了一种新的冷却介质测试探头。本文应用求解导热反问题的ТИХОНОВ正则化法,研究探头表面与介质之间的不稳定沸腾换热问题。经实验验证,所得出的非线性导热反问题的数值解与检验探头的实测温度能很好地吻合。

Abstract: The Technical Committee "Scientific and Technological Aspects of Quenching" within the International Federation for the Heat Treatment of Materials has recommended a new quench test probe. This paper applies the Tikhonov regularizing algorithm for solving inverse heat conduction problems to study the unsteady boiling heat transfer processes between the probe's surface and quenching medium. The numerical solutions obtained .are stable and in accord with the measured check temperatures.
