ABSTRACT CTS-9400647 A. Haji-Sheikh The proposal is to explore an inverse method for solving three-dimensional heat conduction problems based on Green's theorem. Verification of the method is proposed by both forward solution of the inverse problem and by experiment. Solutions to inverse problems are necessary when property data is to be recovered from temperature and/or heat flux measurements at surfaces, and accurate three-dimensional methods are not available. The work has application in providing real-time control of spray cooling in metallurgical heat treating and the cooling of high temperature materials in manufacturing processes as well as in advanced electronic cooling.

摘要CTS-9400647 A. Haji-Sheikh该提案是探索基于Green定理解决三维热传导问题的反向方法。 该方法的验证是通过反问题的正向解和实验提出的。 当要从温度和/或表面上的热通量测量中恢复属性数据时，需要解决反问题的解决方案，而准确的三维方法则不可用。 这项工作已应用于在冶金热处理和制造过程中的高温材料以及高级电子冷却中对喷雾冷却的实时控制。
