“…The re-plating algorithm achieved the same calculation as the plating algorithm in 113.4s, or two-thirds the CPU time. When the SRPA is used, CPU time for TEA calculation was reduced by factors of 2, 7, and 16, when compared with the plating algorithm, [20]. depending on the reduction and truncation parameters of the SRPA.…”

“…El Hitti et al proposed the simplified plating algorithm (SPA) in order to reduce CPU time for calculating TEAs for radiative heat transfer. The SPA is an accelerated version of the plating algorithm in which CPU time for TEA calculation is reduced by a factor between 6 and 34 [20]. The plating algorithm is easily coded and occupies less memory space than the widely used matrix inversion techniques for calculation of total transfer factors.…”

International audienceGreat efforts have been made to date toward modeling nongray radiative heat transfer accurately. In this article, a new version of the plating algorithm, designated the re-plating algorithm, for total exchange areas (TEAs) calculation from direct exchange areas (DEAs) for nongray radiative problems is presented. The re-plating algorithm calculates TEAs for a given band number b from those of band number b - 1 by performing successive re-plating procedures. The effectiveness of the new algorithm is demonstrated for thermal modeling of an aluminum brazing furnace and a glass treatment furnace. CPU requirements for TEA calculation were reduced significantly
