摘要: 建立了步進式加熱爐內流動、燃燒和傳熱的數學模型.湍流模型采用k-ε雙方程模型,輻射換熱計算采用六通量法,氣相燃燒采用修正EBU模型,流場計算采用Simpler算法.采用上述模型與算法得到了爐內詳細合理的溫度、速度和濃度分布.Abstract: 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.
