Indoor Air Quality (IAQ) in Public Environments

Simulation to Create Safe Life Environment for Citizens

In the context of the pandemic, creating safe environments to resume everyday life is front and foremost. This pandemic has taught us that our infrastructures were not ready, and Indoor Air Quality (IAQ) has become a top priority for all of us.

After many changes in direction, the WHO and other organizations have acknowledged the importance of airborne contagion for the transmission of COVID-19 from aerosols, i.e. droplets exhaled by infected people less than 5 microns in diameter. In any closed environments (schools, theaters, stadium, airports, aircraft, stations, trains, buses, cars, cruises, etc), the concentrations in contaminants can increase due to an improper design of the ventilation/HVAC systems or large recirculation areas typically present to improve thermal comfort.

SIMULIA CFD/Fluid solutions are best-in class for the accurate prediction of droplet transport by airflow. Our solutions can reveal the invisible, helping us at assessing any potential increased risk of contagion, devising strategies to minimize such risks (HVAC system configurations, air purifiers, filters, or simple natural ventilation) and communicating the safer outcomes to the public via high quality rendered animations powered by science.
