Reynolds-Averaged Navier-StokesRANS Reynolds-Averaged Navier-Stokes Equations -- RANS 4 equations; 7 unknowns Similar situation as when we went from Cauchy’s.
Turbulent properties: - vary chaotically in time around a mean value
Turbulent properties: - vary chaotically in time around a mean value - exhibit a wide, continuous range of scale variations - cascade energy from large.
