【摘要】：亞微米細(xì)微顆粒物凝聚技術(shù)是對(duì)亞微米細(xì)微粉塵進(jìn)行阻隔和收集的有效方法。為了對(duì)亞微米細(xì)微粉塵凝聚裝置中含塵氣流流場(chǎng)及顆粒運(yùn)動(dòng)軌跡進(jìn)行模擬,應(yīng)用Fluent軟件,采用格子波爾茲曼模型模擬含塵氣流流場(chǎng),采用離散相(discrete phase models,DPM)模型模擬顆粒運(yùn)動(dòng)軌跡,對(duì)不同速度入口下和不同粒徑的顆粒軌跡分布進(jìn)行了數(shù)值模擬和分析。結(jié)果表明:凝聚區(qū)中的產(chǎn)渦裝置可以產(chǎn)生隨速度變化的不同尺度的渦;隨著顆粒粒徑的減小,越易受湍流作用的影響,碰撞幾率越大。
[Abstract]:Submicron fine particles condensation technology is an effective method to block and collect submicron fine particles. In order to simulate the dust flow field and particle motion trajectory in submicron fine dust condensate device, the lattice Boltzmann model was used to simulate the dust flow field and the discrete phase model was used to simulate the particle motion trajectory by using Fluent software, the lattice Boltzmann model and the discrete phase model were used to simulate the particle motion trajectory. The particle trajectory distribution under different velocity inlet and different particle size is numerically simulated and analyzed. The results show that vortex-producing devices in the condensed region can produce vortices of different scales varying with the velocity, and with the decrease of particle size, the higher the impact probability is, the easier the particle size is to be affected by turbulence.
