通过建立瓦斯流场和细水雾流场叠加的数学模型,在拉格朗日框架下,从细水雾流场在瓦斯输送管道内的均布长度(单喷嘴喷射时细水雾流场均匀布满管道的长度)和混合流场的压降情况两个方面,对不同的喷嘴安装角度进行研究。研究表明,喷嘴0°安装时,细水雾的均布长度和混合流场的压降均优于喷嘴180°安装。所得研究成果为认识混合流场的流动特性,解决输送管道内喷嘴与喷嘴之间的安装距离及喷嘴的安装角度等问题提供了一定的理论依据。
Through the establishment of the mathematical model of superposition of gas flow field and water mist flow field, the uniform distribution of the water mist flow field in the gas transmission pipeline under the Lagrange framework The length of the pipe covered) and the pressure drop of the mixed flow field, the different nozzle installation angles are studied. The results show that when the nozzle is installed at 0 °, the uniform length of the water mist and the pressure drop of the mixed flow field are better than that of the nozzle by 180 °. The research results provide a theoretical basis for understanding the flow characteristics of the mixed flow field, solving the problems of the installation distance between the nozzle and the nozzle and the installation angle of the nozzle in the delivery pipe.
