| Abstract: | An integration technique using number-mesh method based on number theory is derived and stated in detail so as to apply it to the computatison of radiative direct-exchange areas that needed for zonal analysis. Such advantages as higher accuracy and time-saving on computer are thus attainable in comparison with using Gaussian quadrature method to compute radiative direct-exchange areas. The results show that this technique is simpler,more accurate and time-saving than other methods previously used. |
