任意几何形状辐射换热的脉动表面流公式

Fluctuating surface-current formulation of radiative heat transfer for arbitrary geometries

Alejandro W. Rodriguez, M. T. Homer Reid, Steven G. Johnson

摘要:

我们描述了一个波动的表面电流制定的辐射传热,适用于任意的几何形状,直接利用标准的,高效的,和复杂的技术从边界元法。我们验证,以及扩展以前的结果的球体和圆柱体,并计算在一个更复杂的几何形状组成的两个联锁环的传热。最后,我们证明了该方法可以很容易地适应于计算相互作用的物体表面上的热流的空间分布。

英文摘要:

We describe a fluctuating surface-current formulation of radiative heat transfer, applicable to arbitrary geometries, that directly exploits standard, efficient, and sophisticated techniques from the boundary-element method. We validate as well as extend previous results for spheres and cylinders, and also compute the heat transfer in a more complicated geometry consisting of two interlocked rings. Finally, we demonstrate that the method can be readily adapted to compute the spatial distribution of heat flux on the surface of the interacting bodies.
