摘要
利用PHOENICS软件 ,对钝体稳焰瓦斯燃烧器湍流扩散火焰进行了数值计算 ,验证了k ε湍流模型、三气体燃烧模型及综合辐射模型的有效性。探讨了稳焰块直径和火道张角对燃烧器稳焰特性和火焰长度的影响。用数值模拟方法对瓦斯燃烧器湍流扩散火焰进行了研究。
With PHOENICS software using the k-ε turbulent model,the three gases mixing combustion model and the composite radiosity model,numerical simulation study is made on the turbulent diffusion flame of a gas burner with a V-shaped flame holder.The distribution of the temperature, the velocity and the concentration of the flame are got.The result shows that the models selected are valid.It is tended that the backflow region increases and the flame length decreases when diameter of the flame holder and the angle of the flame path become larger .
