Abstract
The building envelope design with louvers that protect it from solar radiation and residual particle matter is an idea for developing a building envelope system with higher performance. It requires designing an air circulation system and creating an environment within the air cavity that minimizes dust residues. Therefore, this research aims to predict the airflow pattern and residual particulate matter through the louvers within the air cavity with the Computational Fluid Dynamics (CFD) program. During the research stage, various parameters were studied, including the size of the air cavity, airflow inlet and outlet openings, the shape of the louvers, and the amount of particle matter remaining in the air cavity. These parameters were measured through four experimental boxes with different specifications to forecast the airflow and particulate matter behavior by applying the SOLIDWORKS 2023 (Flow Simulation) software. The findings indicated that reducing the size of the air cavity leads to higher internal pressure and air velocity. Vertical airflows ascending from the lower to the upper apertures exhibit reduced areas of stagnant air compared to downward airflows. The test box (a.2 ) can effectively remove up to 2 4 % of particulate matter without mechanical intervention. The data acquired from this research is preparatory to advancing building envelope technologies for enhanced efficiency in the future.
