摘要
基于计算流体动力学(Computational fluid dynamic,CFD)的数值模拟方法,在FLUENT软件平台上,应用大涡(LES)模型模拟了升气管插入深度对旋风分离内部流场的影响。计算结果表明,升气管的插入深度对旋风分离器的流场有很大的影响,随着插入深度的增加,切向速度会减小。本次模拟中还出现了旋涡端部的现象,且随着升气管插入深度的增加,旋涡端部的位置也随着下降,这能够增大分离空间,有利于分离。
Numerical approach of computational fluid dynamic （CFD） is conducted to systematically study the effects of the figure of vortex finder on the performance in cyclone separator by using large eddy simulation, discrete phase model in FLUENT software platform. In this study, the end of the vortex （EOV） is investigated. The result showed that the increasing of length of the vortex finder lead to the degrade of location of the end of the vortex（EOV） as well as the decreasing of tangential velocity, which is good at the separation performance.
