辐射传热和传导传热在许多现代机械和制造技术中占据主导地位。自20世纪70年代末以来，Bauman MSTU已经制定了解决复合材料和结构中RCht直接问题（dp）和逆问题（ip）的方法、算法和软件包car&rdquo；（传导和辐射）。求解dp的数值方法、ip的极值语句、残差函数的数值优化和迭代正则化方法构成了“car”方法的理论基础。该软件包“Car”用于研究项目可重复使用运载火箭、“Buran”、“Hopper”、“Large Space Frame”、“Sofora”、“Large Deployable Space Antenna NPO EGS”。目前，软件包“car”是当前航空航天应用先进材料研究和新制造技术开发的基础。在讲座中，我们介绍了RCht IP应用的两个分支。第一个与先进材料热物理性能研究相关的分支。这些陈述被表述为系数Ip。简要介绍了多孔半透明材料的实验技术和复合传热的一些特点。第二个分支与设计陶瓷和玻璃的新制造技术有关。这些描述被表述为边界IP，并假定玻璃表面入射热流的时间变化。在开发玻璃陶瓷红外退火、热抛光和烧结三种热处理技术的框架下，进行了数学建模。

| 课程简介: |
The radiative and conductive heat transfer (RCHT) dominates in a lot of modern machines and manufacturing technologies. At Bauman MSTU since the end of 1970’s there have been worked out methods, algorithms and software package “CAR” (Conduction and Radiation) for solving direct problems (DP) and inverse problems (IP) of RCHT in composite materials and constructions. Numerical methods of solving DP, extreme statements of IP, numerical optimization of residual functionals and iterative regularization methods form the theoretical base of the package “CAR” approaches. The package “CAR” was used for researches on project reusable launch vehicles “Buran”, “Hopper”, large space frame “SOFORA”, large deployable space antenna NPO EGS. For today the software package “CAR” is the base for the current studies of advanced materials for aerospace applications and in development of new manufacturing technologies. In the lecture two branches of RCHT IP application are presented. The first branch connected with studies of advanced materials thermophysical properties. The statements are formulated as coefficient IP. Short description of experimental technique and some features of combined heat transfer in porous semitransparent material are given. The second branch connected with designing new manufacturing technologies for ceramics and glass. The statements are formulated as boundary IP and assume the determination of time variation of incident heat flux on the glass surface. Mathematical modelling have been performed in the frame of development three heat treatment technologies as infrared annealing, thermal polishing and sintering of glassceramic.
