辐射传热(heattransferbyradiation) 温度高于绝对零度的物体内的带电粒子振动或转动时向空间辐射出电磁波,而另一物体接受到电磁波,并把它转变为热能,这样就形成了辐射传热。 温度为T、表面积为A的物体在单位时间内的辐射的热量q=AT4,其中为发射率,与物体的材料和它的表面状况有关,是斯特藩-玻尔兹曼常数,=56.710...
当一面积为A1、温度为T1的物体被另一温度为T2的物体包围时,两物体之间的辐射传热为q=A1F1-2T24-T14。这篇辐射传热heattransferbyradiation物理小百科知识,你推荐给朋友了么?*;

1、第五章 辐射换热(Radiation Heat Transfer) 5.1辐射的基本概念 一、辐射的本质 辐射物体通过电磁波传递能量的过程 热辐射是由于物体内部微观粒子的热运动状态改变时,而将部分内能转变成电磁波的能量发射出去的过程。热辐射的三大特点 可以在真空中传播; 能量形式在传播过程中发生了变化 一切物体只要温度大于0K,就...
Heat Transfer: Conduction, Convection, and Radiation Introduction We have learned that heat is the energy that makes molecules move. Molecule..
In industrial heating, the radiation normally used is in the Ultraviolet-, Infrared-, Microwave- or short Radio wavelength. Click Image to Enlarge Infrared is one of four ways to transfer heat via radiation Infrared is only one in four ways to transfer heat via radiation ...
Heat is transferred by radiation between two well-separated bodies at temperatures of finite difference in vacuum. At large distances the heat transfer can be described by black body radiation, at shorter distances evanescent modes start to contribute, and at separations comparable to inter-atomic spa...
