NO_x生成湍流反应率的二阶矩-PDF数值模拟

Numerical Simulation of NO_x Formation with a Second order moment PDF Turbulence chemistry Model

将对 NOx 生成湍流反应率模拟的二阶矩模型和设定 PDF模型结合起来 ,提出一种氮氧化物生成湍流反应率的二阶矩 - PDF模型 ,以兼顾解决工程问题的合理性和经济性 ,并对甲烷空气燃烧中的 NOx

In order to simulate more reasonably and economically the interaction between turbulence and finite rate kinetics,a second order moment PDF turbulence chemistry model for NO x formation is proposed.The PDF transport equation model,simplified PDF model,simplified PDF model with partial equilibrium,and second order moment model,which are all used to simulate the turbulence chemistry in NO x formation,are compared with the second order moment PDF tubulence chemistry model.The NO x formation in methane air combustion is simulated numerically with the second order moment PDF turbulence chemistry model.
