Radiation in Enclosures

Aristide Mbiock

During the last half century, the development and testing of prediction models of combustion chamber performance have been an ongoing task at the International Flame Research Foundation (IFRF) in IJmuiden in the Netherlands and at many other research organizations. This task has brought forth a hierarchy of more or less standard numerical models for heat transfer predictions, in particular for the prediction of radiative heat transfer. Unfortunately all the methods developed, which certainly have a good physical foundation, are based on a large number of extreme sim­ plifications or uncontrolled assumptions. To date, the ever more stringent requirements for efficient production and use of energy and heat from com­ bustion chambers call for prediction algorithms of higher accuracy and more detailed radiative heat transfer calculations. The driving forces behind this are advanced technology requirements, the costs of large-scale experimen­ tal work, and the limitation of physical modeling. This interest is growing more acute and has increased the need for the publication of a textbook for more accurate treatment of radiative transfer in enclosures. The writing of a textbook on radiative heat transfer, however, in ad­ dition to working regularly on other subjects is a rather difficult task for which some years of meditation are necessary. The book must satisfy two requirements which are not easily reconciled. From the mathematical point of view, it must be written in accordance with standards of mathemati­ cal rigor and precision.

The theoretical results successfully predict the trends observed in the experimental data. It is observed that the contribution of the radiation heat transfer is on the order of 50% of the total heat transfer for the tested enclosures. As such, Enclosures and Radiation Gills - Unidata

The use of electronical devices is increasing, as is the exposure to a wide range of frequencies. Radiation and immunity have to be taken into account in early stages of the development of new products. In many cases EMI problems cannot be solved at the PCB level alone and instead, enclosures and cables have to be shielded as well. THE INTERACTION BETWEEN RADIATION …
