Sure they do, it's just called fluid dynamics and thermodynamics. Enough to fill up about 1/3 of a mechanical engineering degree, if you're really into it (most aren't).
Not that there's a lot of historical context to things as far as which people did what - most of that sort live on in names of techniques and methods (Rankine cycle, de Laval turbine, Carnot efficiency, etc.)
