TLDR
In this paper, the authors considered both black and diffuse gray-body radiation and obtained a simple relation between the two types of radiation, and solved the energy equation by three methods: use of a separable kernel, numerical integration, and variational methods.Abstract:
Thermal radiation was considered from the inside surface of a heated cylindrical enclosure. A specified heat input was imposed at the enclosure wall and the surface temperature distribution was determined. The analysis considered both black and diffuse gray-body radiation and obtained a simple relation between the two. The energy equation, a linear integral equation, was solved by three methods: use of a separable kernel, numerical integration, and variational methods. (auth)read more

A Survey of Recent Developments
TL;DR: Nowzad and Baker as discussed by the authors presented a survey of recent developments in Africa and Latin America respectively, and analyzed the recent proliferation of regional and sub-regional organizations in these two continental areas, indicative of the ongoing efforts to mold viable political institutions out of a confusing welter of nationalistic goals and aspirations.

Inverse surface radiation analysis in an axisymmetric cylindrical enclosure using a hybrid genetic algorithm
Ki Wan Kim,Seung Wook Baek +1 more
TL;DR: An inverse boundary analysis of surface radiation in an axisymmetric cylindrical enclosure is conducted in this paper, where the net energy exchange method was used to calculate the radiative heat flux on each surface, and a hybrid genetic algorithm was adopted to minimize an objective function, which is expressed by the sum of square errors between estimated and measured or desired heat fluxes on the design surface.

Coupled radiative and conductive heat transfer across honeycomb panels and through single cells
TL;DR: In this paper, the total heat transfer across a flat plate solar collector was studied experimentally and theoretically, and the theoretical approach proposed several models, established their governing equations, and solved the equations by either numerical or analytical methods.
