A new universal theory for flow instability and turbulent transition is proposed in this … Witrynaproposed that the necessary condition for the turbulence transition is that there is an energy gradient in the transverse direction of the main flow. 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.
