摘　　要：在分析比较了 Monte Carlo 法和段法各自优缺点的基础上,发展了 MonteCarlo 法与段法相结合的火焰炉传热数学模型。用Monte Carlo 法计算全交换面积;推导了长方体分段时空间能束传播方向的角度变换公式;以实验炉的具体条件建立了炉内传热模型,在模型中考虑了炉气回流及炉内析热场。模型计算结果与实验结果吻合较好。本模型克服了 Monte Carlo 法与段法各自的缺点,是简化段法并保持其精确性的一种新途径。Comparing all--sidedly the Monte Carlo method to zone method, the authors de-velop a new mathematical model by way of combining the two methods to describe the heat transfer in flame. The total exchange areas are calculated by MonteCarlo method, and the zoned energy equilibrium system of equations is de-rived for solving the temperature field in furnace. The calculation resultsbased on specified conditions show that the model developed is able to takeadvantages from both methods and get rid of their disadvantages. This modelwill be a new way available to heat transfer in flame furnace with accuracykept to.
