I'm just plain curious & trying to get my head around it (I've played around with procedural noise textures & the like). Does the navier-stokes function (or functions like it) operate on a repeating (wrapped around) grid or is there a more obvious method that I'm missing?

Navier-Stokes is a set of non-linear differential equations, not a function. It's extremely hard to analytically solve the equation (unless you give it some extremely simplifying constraints), so the best you can do is solve it discretely and iteratively. Then you're just looking at the neighborhood of a given point in space and time to compute the next value at that point, so it could really be any topology.
