Origin of turbulence - energy gradient theory
WitrynaThe fully developed turbulence is found to be composed of singularities of flow field. The mechanisms of flow stability and turbulent transition are described using the energy gradient theory, which states all the flow instability and breakdown resulted from the gradient of the total mechanical energy normal to the flow direction.

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.

Now, we prove this necessary condition is correct at least for parallel flows.
