The spreading of a disease largely occurs in buildings or in collective transport. The microenvironment flow processes around people contribute to the cross-infection risk, for example when two persons are standing close to each other. The cross-infection risk is also dependent on the macro-environment e.g. distribution of velocity and turbulence in the room, particularly when the background airflow is strong. The surrounding temperature and the presence of a vertical temperature gradient can also modify airflows in the microenvironment and subsequently influence the cross-infection risk. This work is based on a fully mixed flow in a room without a vertical temperature gradient, considering different room temperatures.

Exhalation flow and aerosol distribution are studied by smoke experiments and the cross-infection risk is expressed as concentration in the susceptible breathing zone normalized by the concentration in the room.
