WebDec 21, 2007 · Fanno flow requires a friction factor to be exact, so is it possible to consider a friction factor in the solver, or is it accounted for in the turbulence model? Can Rayleigh flow be turbulent? Rayleigh flow neglects friction, but CFD solver apply wall laws, thus creating friction or is that a different 'type' of friction? Any thoughts? WebDec 2, 2024 · The Rayleigh-Taylor instability is an instability of the interface separating two immiscible fluids ; the densest of which rests on the lightest. Following a disturbance of the interface, the dense fluid enters the light fluid. The interface growths with a characteristic “mushroom” shape. For example, Rayleigh-Taylor instability manifests ...
