The RNG k-ε turbulence model in scSTREAM is used to simulate and analyze atmospheric diffusion of pollutants for different layout schemes. For a single cooling tower arrangement, the concentration distribution is a standard Gaussian distribution in the distance between release point and cooling tower, and its concentration is also significantly higher than those of the other three arrangements. In addition to the S-shaped arrangement, the other three solutions form a steep drop effect on the leeward side of the cooling tower. In the distribution of pollutants on the leeward side of the cooling tower, the concentration results of the single cooling tower arrangement are smaller than those of the other three schemes, mainly because a large amount of pollutants enter the cooling tower body and then discharge from the top of the cooling tower, causing a sharp concentration decrease on the leeward side., authors=WANG Xuan^1,2, Wei Guoliang³, ZHANG Yanan³, TAO Weiding³, WANG Dezhong², WANG Bo³, authorsList=WANG Xuan, Wei Guoliang, ZHANG Yanan, TAO Weiding, WANG Dezhong, WANG Bo, authorCompany=1.
