Despite its great scientific and technological importance, wall-bounded turbulence is an unresolved problem in classical physics that requires new perspectives to be tackled. One of the key strategies has been to study interactions among the energy-containing coherent structures in the flow. Such inter...
Direct simulations have become indispensable tools in turbulence research, and, in the last two decades, especially so for the study of wall-bounded turbulence. Early simulations dealt mostly with the viscous and buffer layers near the wall, because their Reynolds numbers had to be necessarily ...
Wall-bounded turbulence at high Reynolds numbers. Measurements are reported that give new insight into the behavior of turbulent wall-bounded flows at high Reynolds number. Turbulent pipe and boundary laye... M Vallikivi - Princeton University. 被引量: 0发表: 2014年 Reynolds Number Effects in Wa...
This article discusses the description of wall-bounded turbulence as a deterministic high-dimensional dynamical system of interacting coherent structures, defined as eddies with enough internal dynamics to behave relatively autonomously from any remaining incoherent part of the flow. The guiding principle is...
Consequently, we evaluated existing nonlinear two-equation turbulence models based on our DNS of streamwise and wall-normal rotating channel flows. Using the results of evaluation, we have improved the modeled expression for Reynolds stress, in which a new cubic-type nonlinear model has been ...
