摘要
玻璃内部的传热是个非常复杂的现象,在高温下,玻璃内部主要通过容积辐射传递热量.本文从光子导热的角度介绍玻璃内部的辐射过程以及处理方法,说明有效导热系数K_e在处理实际传热问题中是个非常有用的概念.
Heat transfer in glass is a very complex phenomenon. At high temperature, most of the thermal energy is delivered by volume radiation in glass. Radiation in glass and dealing method are described from photon conduction in this paper. It concludes that effective conductivity K_e is a very useful concept in dealing with practical heat transfer problems.
