Slide 1 Reynolds-Averaged Navier-Stokes Equations -- RANS 4 equations; 7 unknowns Similar situation as when we went from Cauchy’s eq to N-S eq Aj = eddy viscosity [m2/s]…

Turbulent properties: - vary chaotically in time around a mean value exhibit a wide, continuous range of scale variations cascade energy from large to small spatial scales…
