چکیده
A new scaling is derived that yields a Reynolds number independent profile for all components of the stress in near-wall region wall bounded flows, including channel, pipe and boundary layer flows. The demonstrates important role played by shear fluctuations how large eddies determine dependence turbulence behavior.

Introduction: scaling and structure in high Reynolds number wall-bounded flows.
On bou *A According to Lighthill (1995), Prandtl’s (1904) boundary layer has had the same transforming effect on fluid dynamics as Einstein’s 1905 discoveries had on other parts of physics, which, by the way, were celebrated in 2005 as the World Year of Physics. That the boundary layer becomes turbulent was formally known to Blasius (1908), though, of course, the origin of turbulence in a pipe ...
متن کاملContribution of Reynolds stress distribution to the skin friction in wall-bounded flows
A simple expression is derived of the componential contributions that different dynamical effects make to the frictional drag in turbulent channel, pipe and plane boundary layer flows. The local skin friction can be decomposed into four parts, i.e., laminar, turbulent, inhomogeneous and transient components, the second of which is a weighted integral of the Reynolds stress distribution. It is r...
متن کاملA New Scalar Reynolds Stress Model For Non-Isothermal Wall Bounded Turbulent Flows
The present investigation concerns the development of advanced scalar turbulence modeling approaches and their application to the calculation of non-isothermal wall-bounded flow phenomena. A new scalar modeling technique based on scalar turbulent scales is proposed and implemented at a second-order modeling approach. Instead of the classical analogy concept between the mechanical and the scalar...
متن کاملNear-wall Scaling for Incompressible and Compressible Flows
The paper presents near-wall scaling in incompressible and compressible flows. It concentrates on flows with streamwise pressure gradients which render traditional scaling inapplicable. For incompressible flows a scaling for the velocity profiles is introduced based on both the friction velocity and the pressure gradient. For compressible flows a scaling is developed for the velocity and the te...
متن کاملSkin Friction in Simple Wall - Bounded Shear Flows in Large Reynolds Number Limit
Expressions for variation of skin friction with Reynolds number in fully developed turbulent channel/pipe flows and in zero pressure gradient boundary layers are derived. The proposed in this paper asymptotic (Reδ = δ(x)U ν → ∞) theory is formulated as a convergent perturbation expansion in powers of small dimensionless parameters dδ dx → 0 and u∗ U → 0 applied directly to the Navier-Stokes equ...
