Abstract

Abstract: A new angular quadrature set is proposed for the discrete ordinates method for radiative heat transfer.The numerical test comparison of the new approach with the series of traditional quadrature set, and T_N quadrature set appeared in literature recently indicates that,the accuracy of successive spherical ring arithmetical progression dividing method is much higher than that of traditional series quadrature set,and is at the same order with that of T_N quadrature set.
