发展了模拟稀疏液雾燃烧过程的全欧拉模型 ,除了气相各守恒方程在欧拉坐标系下求解外 ,液雾相的质量变化、温度变化以及运动过程也是由欧拉坐标系下的守恒方程描述 ,气相和液雾相可以采用统一的数值求解方法。液雾相按照初始尺寸分组 ,每一组液雾相均由一组守恒方程描述 ,通过求解液雾相的数密度方程 ,可以得到欧拉坐标系下各网格点处某一组液雾相的液滴的质量和温度。 The whole Euler model of simulated sparse liquid mist combustion is developed. In addition to solving the conservation equations of gas in the Euler coordinate system, the mass, temperature and movement of the liquid phase are also determined by the conservation equation Description, gas phase and liquid mist phase can be unified numerical solution method. The liquid mist phases are grouped according to the initial size. Each liquid mist phase is described by a set of conservation equations. By solving the numerical equation of the density of the liquid mist phase, one of the liquid mist phases at each grid point in the Euler coordinate system Of the droplet mass and temperature.
