Our aim is to simulate and control how air flows when there is a mix of common air particles and aerosol particles including air pollutants indoors. The simulation models a room (with or without furniture depending on what the user chooses) either closed or with windows or doors open to aid with reopening different sectors as governments around the world ease COVID-19 lockdown measures.

We looked at how air particles spread around in a closed environment in MATLAB, this can be transferred to a web page where users from around the world can add different furniture and change the room, which hopefully gives them an idea of how office rooms can be changed to help reduce the spread of COVID-19, like adding vents or air conditioners to control airflow. Not only can the user choose the room layout, they can also change the air particles' and pollutants' densities, masses, and velocities.
