• The system of cylinder-rows is favored in heat-exchangers or radiators, but estimation of its radiative transfer is often unavailable due to insufficiency of data provided in few reports. The purpose of this study is to identity the characteristics of radiative transfer in such cylinder-row systems. Analysis is made on two-row gray circular cylinders arranged on square-centers to obtain local radiative fluxes. Then the influences on radiative transfer are found of emissivity and the center-to-center distance of cylinders. Approximate solutions are additionally evaluated to compare with the numerical solutions. The same procedures are employed in one-row cylinders to see the influence of the number of rows. In black, semi-infinite-row cylinders (arranged infinitely from the first row on one side), variations in radiative heat rate are evaluated in several rows from the initial, in the range where the heat transfer is significant.
