Thank you very much for this response. I found it helpful.

I've been reading some of the research papers on waves and fluids from the late-1800s. One I went through a couple weeks ago was Reynold's 1883 paper on turbulent flow [1]. It's interesting going through old papers. They're a lot more casual and meandering than modern ones, and I feel like I get more insight into how the sausage is made that way.

I still wonder about some things, though. I'm familiar with the main CG fluid techniques, and it seems that they are used in real scientific simulations on occasion. For example, Smoothed-Particle Hydrodynamics have been used in ocean wave simulations, and they appear to validate against wave tank experiments. I actually was going to use them myself for simulations of wave-swept environments.

But, aside from bumping into Bridson at a conference, I haven't gotten many chances to speak to someone who really knows fluids well. I was wondering if you'd be willing to answer some more questions of mine about how the CG methods compare to DNS, LES and RANS. If so, send me an email and maybe we can chat about it. My address is just my HN username at gmail.com.
