Entropic-Skins Geometry to Describe Wall Turbulence Intermittency

Autor: Diogo Queiros-Conde, Johan Carlier, Lavinia Grosu, Michel Stanislas

Publikováno v: Entropy, Vol 17, Iss 4, Pp 2198-2217 (2015)

In order to describe the phenomenon of intermittency in wall turbulence and, more particularly, the behaviour of moments and and intermittency exponents ζP with the order p and distance to the wall, we developed a new geometrical framework called �

International audience; Spring frost has been recognized as the most harmful weather hazard for agriculture. One way to fight it back is using a wind machine - a 6-m diameter blowing fan atop a 10-m mast. It rotates on itself in approximately 4min30s

Spring frosts occurring after budburst constitute a significant risk for winegrowers and can lead to severe yield losses. Wind machines can contribute to protecting vineyards against these frost events. However, the efficiency of wind machine parks d

This paper provides preliminary results on the closed-loop control of a spatially developing mixing-layer induced by two parallel incident streams with different velocities. The goal of the control law was to stabilize the flow around a desired state

Buoyancy effects on the turbulent mixing and entrainment processes were analysed in the case of a stratified plane shear layer between two horizontal air flows in conditions leading to relatively low values of the flux Richardson number ($|Ri_{f}|_{m
