摘要
建立湍流燃烧的“双流体”数学模型 ,用于一维湍流预混稳态火焰的描述。假定燃烧火焰由冷的反应物 (预混气体 )和热的生成物 (燃烧产物 )组成 ,它们既有各自的属性 ,又相互作用 ,进行热量、质量和动量的交换。采用Patankar和Spalding的Phoenics计算程序来求解该数学模型 ,成功地模拟了一维湍流预混火焰的压力场、密度场、速度场。
The two-fluid mathematical model of turbulent combustion is built,which to depict steady state one -dimensional turbulent premixed flame.The flame is assumed to consist of a cold reaction fluid (premixed gas) and a hot product fluid (combusted gas), each characterized by its properties and interacting through the exchange of mass,heat and momentum.Using Phoenics calculation programme developed by Patankar and Spalding,the distribution of pressure,densities,velocities and volume fraction across the duct were successfully simulated.
