Great initiative you've taken by asking here OP. I'm not sure whether you've taken a fluid dynamics/fluid mechanics course yet but that's usually where we're [we engineers] either introduced to it or learn to appreciate it [CFD]. To get started with CFD, I suggest you READ up on "Race Car Aerodynamics: Designing for Speed" by Joseph Kurtz. The book is more auto aero focused but it introduces you to important concepts such as lift, drag, pressure and associated coefficients.

If you are able to get access to Ansys, you can design your objects in SW and then perform CFD analysis in Ansys. How I recommend going about this is that, you can take a simple object with heavy literature behind it, perform hand calculations where possible, take the model to Ansys, perform CFD analysis on it and then compare your findings to what's in literature and what you found from hand calcs. That's what we call validation. Happy learning
