摘　　要：建立了步进式加热炉内流动、燃烧和传热的数学模型.湍流模型采用k-ε双方程模型,辐射换热计算采用六通量法,气相燃烧采用修正EBU模型,流场计算采用Simpler算法. 采用上述模型与算法得到了炉内详细合理的温度、速度和浓度分布.A comprehensive mathematical model for simulating the reacting flow and heat transfer process in a reheating furnace was developed. The model includes the k-Ε two-equation model for turbulenct flow, the six-flux model for radiative heat transfer and the EBU turbulent gaseous combustion model for gaseous reaction. The governing equations are solved by the SIMPLER algorithm. Detailed and reasonable results of the distributions of velocity, temperature and concentration were obtained.
