本文对工程中常见的气固燃烧反应两相流中颗粒弥散现象进行了数值模拟,主要用随机轨道法考虑了气相湍流脉动、Magnus力和煤粉燃烧过程中挥发份的喷射对颗粒运动和弥散的影响、同时给出了有益的计算结果。
In this paper, the numerical simulation of particle dispersion phenomenon in two-phase flow of gas-solid combustion reaction, which is common in engineering, is mainly carried out by stochastic orbital method considering the fluctuation of gas phase turbulent pulsation, Magnus force and volatilization of pulverized coal combustion on particle movement and dispersion At the same time, the useful calculation results are given.
