| Abstract | This research was the study of airflow in model of air pollution treatment using plants by Computational Fluid Dynamic (CFD) analysis as a case study in laboratory. The objective was to explore a suitable plants placement to filtration efficient of air pollution treatment. The sizeof model was 100 x 80 x 30 cm, with air inlet and air outlet of 10 x 10 cm. All model had 4 size panels inside. Three different methods of panel placement were tested consisted of; 1) placing to block airflow, 2) placing to zigzags panels and 3) placing to parallel panels. The inlet air velocity was setup as; 0.5, 1.0, 1.5 and 2.0 m/s, respectively. The parameters were measured consisted of air velocity and air temperature distribution in 12 locations by CFD modeling. It was found that airflow in treatment box model 2 was able to circulate in all locations that had similar average airflow throughout the model. In model 2, the average airflow velocity (top view/front view) was 0.23/0.27, 0.57/0.43, 0.71/0.80 and 0.97/0.96 m/s, respectively. At all velocities of inlet air, airflow passed through all locations and contacted with surfaces of every panels. As a results, there was a high being absorbed by air pollution treatment by plants such as mosses and lichen to assess the concentration of heavy metal in atmosphere. For the temperature distribution, it was found that the model 2 had the most suitable conditions. Therefore, this study found that the model 2 with alternating zigzags panels was the most filtration efficient model for air pollution treatment. The results will be compared with further testing in laboratory. |
