### Some Modeling Stuff

While running George Bryan’s CM1, but I imagine that these will come up in other contexts too. Turbulence Schemes By decomposing the flow into a mean + perturbations and averaging, one obtains the Reynolds-Averaged Navier-Stokes (RANS) equations. These still contain a perturbation term (the Reynolds stress term), and this term is generally dealt with by prescribing it as some … More Some Modeling Stuff
