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。
A “dual fluid” mathematical model of turbulent combustion was established for the description of one-dimensional turbulent premixed steady state flame. It is assumed that the combustion flame consists of cold reactants (premixed gases) and hot products (combustion products), which have their own properties and interact with each other for the exchange of heat, mass and momentum. The mathematical model is solved by Phoenics calculation program of Patankar and Spalding, and the pressure field, density field and velocity field of one-dimensional turbulent premixed flame are successfully simulated.
