I hate to utter his name, so I used DT for [donald trump].
Thermodynamics overlaps with almost everything, but some fields (like energy) more directly than others (ventilation). HVAC is an engineering branch all its own that is taught in some schools (including one university where I taught). Thermodynamics does play a significant role and is pre-requisite.
As a fluid dynamics specialist, I’ve had a great interest in ventilation and airflow, especially in confined spaces, in the context of virus spread, since the pandemic began. We’ve had quite the extensive discussion of that here on FTC going back to early last year, but mostly on another thread. The discussion included experimental observations, computational fluid dynamics (CFD), and synthesized data involving airborne releases in enclosed spaces.
I think it’s this one:

By the way, I’m glad that you’ve joined this thread.
