The transport of virus-laden aerosols from a host to a susceptible person isgoverned by complex turbulent airflow, and physics related to breathing,coughing and sneezing, mechanical and passive ventilation, thermal buoyancyeffects, surface deposition, masks, and air filtration. In this paper, we studythe infection risk via airborne transmission on an urban bus using unsteadyReynolds-Averaged Navier--Stokes equations and a passive-scalar model of thevirus-laden aerosol concentration. Results from these simulations are directlycompared to the widely-used well mixed model, and show significant differencesin the concentration field and number of inhaled particles. Specifically, inthe limit of low mechanical ventilation rate, the well-mixed model willover-predict concentration far from the infected passenger, and substantiallyunderpredict concentration near the infected passenger. The results reportedherein also apply to other enclosed spaces.
