Laminar superlayer

Tīmeklisviscous or laminar in nature. This layer was termed the 'laminar superlayer' by Corrsin & Kistler (1955), and they estimated that its thickness may be as small as the Kolmog0rov viscous lengthscale. However, they equated the laminar superlayer to the 'turbulence front', the layer across which all major changes between irrota- Tīmeklis2011. gada 29. dec. · Published: 29 December 2011 Laminar superlayer in a turbulent boundary layer N.
