Now, we prove this necessary condition is correct at least for parallel flows. If the gravita-tional energy is neglected, the total energy gradient in transverse direction is ∂ ∂y p+ 1 2ρV 2.
Witryna26 mar 2024 · It is suggested in energy gradient theory that the amplification of local turbulence phenomenon would lead to the whole domain loses its stability. In the current case, the natural convection cannot be restricted so that the fluid tends to be turbulence, and this phenomenon is in good agreement with energy gradient theory.
