ROLE OF DISPERSION IN THE PROCESSES OF RADIANT EXCHANGE OF ENERGY,
Abstract
The various problems in the theory of radiant exchange of energy lead to integral and integro-differential equations which have a very complicated mathematical structure. A strict and precise solution of these problems is not possible for the time being. Therefore all theoretical investigations of the different problems in radiant exchange of energy undertaken up to the present time in weakening media start from a number of simplified assumptions. Among such premises there is the assumption about the absence of dispersion in a medium (a purely absorbane one). Due to this as applicable to heat-technology problems, the character of the influence of dispersion in the process of radiant exchange has remianed unsolved in both qualitative and quantitative relationships. In fact each real medium to some extent possesses the property of dispersion, as a result of which the clarification of the role of dispersion or radiation in the radiant exchange of energy affords theoretical and practical interest. In connection with this, in this article an attempt is made also to fill the gap noted and to analyze the role of dispersion as applicable to the transfer of radiant energy in a plane-parallel stratum of a weakening medium.
