基于高斯烟羽模型对空气中的PM_(2.5)进行研究

Study of PM_(2.5) in air based on Gauss plume model

根据实际情况,研究空气中PM_(2.5)浓度持续增加情况。首先,建立空气中PM_(2.5)的高斯烟羽模型;其次,根据广东省全年气候实际情况,确定模型中的扩散系数σ_y与σ_z;最后,通过MATLAB软件,数值模拟已得出的高斯烟羽模型。

According to the actual situation, the continuous increase of PM_(2.5) concentration in the air was studied. First of all, build Gauss plume model PM_(2.5) in the air; secondly, according to the actual situation of Guangdong province climate throughout the year, and determine the diffusion coefficient σ_y and σ_z in the model; finally, through the MATLAB software, Gauss plume model numerical simulation has been obtained.
