Query: High-resolution large-eddy simulation of indoor turbulence and its
  effect on airborne transmission of respiratory pathogens; model validation
  and infection probability analysis   High-resolution large-eddy simulation (LES) is exploited to study indoor air
turbulence and its effect on the dispersion of respiratory virus-laden aerosols
and subsequent transmission risks. The methodology is applied to assess two
dissimilar approaches to reduce transmission risks: a strategy to augment the
indoor ventilation capacity with portable air purifiers and a strategy to
utilize partitioning by exploiting portable space dividers. To substantiate the
physical relevance of the LES model, a set of experimental aerosol
concentration measurements are carried out, and their results are used for
validating the LES model results. The obtained LES dispersion results are
subjected to pathogen exposure and infection probability analysis. Wells-Riley
probability model is extended to rely on realistic time- and space-dependent
concentration fields to yield time- and space-dependent infection probability
fields. The use of air purifiers leads to greater reduction in absolute risks
compared to the analytical Wells-Riley model, which fails to predict the
original risk level. However, the two models do agree on the relative risk
reduction. The spatial partitioning strategy is demonstrated to have an
undesirable effect when employed without other measures. The partitioning
approach may yield positive results when employed together with targeted air
purifier units. The LES-based results are examined in juxtaposition with the
classical Wells-Riley model, which is shown to significantly underestimate the
infection probability, highlighting the importance of employing accurate indoor
turbulence modeling when evaluating different risk-reduction strategies.
