Fluid mechanics is a standard course in many undergraduate engineering curriculum. A quick Google search reveals lots of open-source and downloadable pdfs of printed texts.

Mr_overalls has the overview idea covered. I might add that if you start with the Reynolds transport theorem, you can’t go wrong, but that might be the wrong-math-way-around for you.

Are there particular aspects you are interested in?

E.g. Computational methods

Turbulence

Topology / geometry

Shocks and expansions

Superposition, radiation/diffraction, added mass

Analogues with other systems

Some of this stuff involves simplifying assumptions. Sometimes those reveal neat corners of behavior. (E.g. the superposition business)

Some of it might be better introduced qualitatively at first, like say turbulence. It all depends where you are.

By the way, I don’t know some great amount of this stuff at some expert level. I may be able to guide you in some direction of interest is all.

I wish I knew of an overview which scanned across all this funny behavior but some is pretty widely separated.

Naval architecture text books focus on the linear aspects, and the free surface of course.

Cfd (computational fluid dynamics) just about has to deal with “everything else” except the topology and “geometry of” (physics, mechanics, fluids, etc) which kind of lives the hermit life, like the quaternions or geometric algebra or something.
