摘要
基于数学物理思想和热传导理论,对炼油厂尾气燃烧模型进行优化。假设为连续性火源,利用粒子经典的扩散方程,得到了炼油厂的火势蔓延函数N(r,t)及在t时刻距离井曹底部r处的烟雾扩散密度随时间的变化规律。最后,假定烟雾扩散是以烟团为基本状态的方式进行,并对烟雾扩散进行了必要的简化,从而建立了高斯扩散模型,并利用MATLAB软件进行仿真模拟,得到了烟雾在近地面扩散的浓度随时间的分布函数图。
Based on Mathematical and Physics method and Heat conduction theory,the optimization of combustion model of the oil refinery gas are studied.Under the assumption of continuous of fire,using the diffusion equation of classical particles,the fire spread function N(r,t)of oil refinery and the change rule of smoke diffusion density are obtained at the bottom of the distance r at any time t.Finally,we assume that the smoke diffusion take the form of group as the basic state of smoke and simplify the smoke diffusion,then the gaussian diffusion model is established.And using MATLAB simulation,the concentration distribution function diagram of the smoke near the ground is obtained.
