摘要
利用计算机数值计算来模拟氮氧化物的生成和优选降低氮氧化物的各种措施,已经受到广泛重视.如何建立合理而经济的数学模型,是其中的关键问题之一.本文从热NO和燃料NO两方面着重介绍了近年来湍流燃烧NO生成湍流反应率数学模型及数值模拟的研究现状及发展趋势,对模拟结果进行了分析,并给出了比较详细的模型方程及代数表达式,便于相关研究人员与工程技术人员参考.
As a method of optimum design in reducing pollutant emission of combustion, the numerical simulation of NO formation in turbulent combustion is playing more and more important role. One of the key problems is to establish reasonable and economic mathematical model. Based on resent research results reported by different researchers, the chemical reacting mechanism and current status of mathematical model of NO formation in turbulent combustion is reviewed from thermal NO and fuel NO, and computational results are analyzed. The detailed model equations and algebraic formulas of NO formulation are also given for later reference.
