Sentry buildings have windows that are often open to facilitate communication between personnel. It also provides the possibility for the intrusion of pollutants such as vehicle exhaust emissions. To prevent the intrusion of outdoor pollutants and create an excellent indoor environment, internal circulation with double-attached ventilation (IC-DAV) and external circulation with double-attached ventilation (EC-DAV) are proposed for such buildings, and the isolation effect of two attached ventilation modes on pollutants is compared with that of natural ventilation. A computational fluid dynamics (CFD) method was used to simulate the transportation process and indoor distribution of outdoor pollutants intruding into sentry buildings from the regular openings under different outdoor wind directions, wind velocities, and states of the doors and ventilation modes. The results indicate that the leeward airflow of the three wind directions caused the largest pollutants to invade the room. The
Researchers in MIT’s Department of Mechanical Engineering are using cutting-edge computing and machine learning techniques to re-imagine how the products, systems, and infrastructures we use are designed.
