Techno-Ecological Synergy (TES) is a technique for including ecosystems in industrial processes design. One of the main participants in TES is the forest ecosystem, which is able to reduce air pollution emitted during industrial processes. We tested the relative efficiency of different designs of forest buffers around an industrial complex in absorbing potential aerosol pollution and improving air quality downwind under unstable and stable conditions. We simulated the interactions between the forest-buffer belt and the atmosphere using the Parallelized Large Eddy Simulation Model (PALM). Three canopy-structure set up were considered: a homogenous canopy, canopy strips parallel to the wind and canopy strips perpendicular to the wind. For each canopy strip scenario, we considered thin, intermediate, and wide strips, while the space between strips equals to the strip’s width. Sparse and dense canopies were simulated for each case. The results showed that strips perpendicular to the wind direction had a larger scalar uptake than parallel strips, and sparse canopies are being more efficient than dense canopies in cleaning the air. Also, more deposition occurred under stable conditions which was simulated for dense canopies. Those results can be explained by canopy-induced turbulence structures that couple the air within and above the canopy and lead to more effective leaf area where this coupling is stronger.
