Passive scalar cascade in the intermediate layer of turbulent channel flow for
Emanuele Gallorini, Shingo Motoki, Genta Kawahara +1
Similarities and differences between Kolmogorov scale-by-scale equilibria/non-equilibria for velocity and scalar fields are investigated in the intermediate layer of a fully develo…
