>It would be nice if there were some way to validate the modeling with real-world monitoring, but that seems unlikely to me. And until we have an estimate of the infective dose, and of the range of viral concentrations in emitted aerosols, that would probably offer little useful guidance in any case.
These are key points. I appreciate that people are thinking about the shape of the space that particles are moving in. My experience in collecting particle concentration data in classrooms is that shape and size of the room are an important factors in airflow patterns. But I agree with Peter that there are more important fundamental data we will need before we can make good use of fluid flow principles.
