【摘要】 <正> 为得到锅炉燃烧室三维空间烟气温度和壁面热流分布,需求解三维能量方程: ▽·(ρUCpT)=▽·(λT▽T)+S_Q (1) 炉内换热Monte Carlo解法是把燃烧室划分成体积为△V许多区域,各区域之间辐射热交换用一组可能途径的随机抽样进行模拟计算。能量方程中流动项和湍流导热项则写成差分方程形式。最后求解由各区域能量方程所组成的非线性联立方程组。更多还原

【Abstract】 This paper analyses the convergence of three different methods of solution by iteration in mathematical modelling. In order to select initial point of radiative bundle in mathematical modelling comparison calculationsin detail have been made from the view point of radiation from gas having a finite volume. Two types of mathematical description of luminous flame have been introduced into mathematical modelling and a primary theoratical analysis has also been made.更多还原
