"%22The paper deals with mathematical description of heat transfer through radiation in cylindrical finned tubes of natural gas cooler with subsequent proposal for software support of calculation of heat-energetic parameters. Basic precondition for exact determination of heat flows is a thorough analysis of radiation shape factors. The paper has taken into account only mutual reflection of radiation flows between elementary grey areas. Subsequently, implementation of designed dependences into supporting software tool NGS (Natural Gas Cooler) is described. While presupposing omission of radiation influence on heat transfer in natural gas coolers, dependences of deviations on calculation were designed with considering radiation under particular operational conditions that refer to the possibility of radiation omission between individual elements of finned surfaces.%22"@en . .
