I can start to study was debating with you![translate] aMost of the theory of turbulent flow and its modelling was initially developed by careful examination of the turbulence structure of thin shear layers. 大多数湍流和它塑造的理论由稀薄的剪层动荡结构的仔细的考试最初开发。[translate]...
The theory for the Single-Phase Flow, Turbulent Flow interfaces is described in this section:• Turbulence Modeling • The Algebraic yPlus Turbulence Model • The L-VEL Turbulence Model • The k-ε Turbulence Model • The k-ω Turbulence Model • The SST Turbulence Model ...
In this paper the spatial variations and spectral structure of steady-state turbulent shear flow in channels are investigated without the introduction of empirical parameters. This is made possible by the assumption that the non-linear momentum transport has only stabilizing effects on the mean field ...
Turbulent Shear Flows I || Theoretical and Experimental Investigations of Turbulent Flows with Separation Theoretical and experimental studies are reported on a turbulent flow in a two-dimensional channel of aspect ratio 1:16 in which a square obstacle of half the channel height was located. A one...
It is well known that in a turbulent flow between two parallel flat plates, the horizontal mean velocity varies logarithmically with height (the so-called 'logarithmic-law-of-the-wall'). The law of the wall is a description of the mean velocity profile in wall bounded flows and has been ...
region of turbulent flow is shown that is embedded in a laminar plate flow. It can clearly be seen that the turbulence-dependent flow disturbances are Fig. 17.3 Flow forms of the laminar flows around a cylinder Fig. 17.4 Turbulent spot to illustrate the transitional, laminar-to-turbul...
In this paper a new turbulent lubrication analysis has been derived which takes into account certain well-established facts concerning turbulent shear flow. Consistent with lubrication-film theory, the nature of the local flow is taken to depend only on local film thickness, surface velocity, and ...
The concept that in a turbulent flow energy exchanges only take place of pulsations of near scales is the basis of macroscopic theory of local turbulence structure. Universality and similarity of small-scale statistical pulsations are inferred from the assumption that the energy exchange is of random...
