Introduction to Radiation Heat Transfer
One of the important research contents of heat transfer is the heat transfer process between two objects that have different temperatures and do not touch each other through electromagnetic waves.
Radiation heat exchange is an important heat exchange method in various high-temperature thermal equipment such as industrial furnaces and boilers. There are two types of common problems: radiative heat transfer between solid surfaces, which depends on the radiation angle coefficient F and the value of blackness ε; radiant heat transfer between the gas and the solid surface, in addition to the F and ε values, also the thickness of the gas And its blackness.
