Control of Turbulent Flows
It is useful for many industrial applications to be able to control turbulence in uid ows, either to reduce it or, in some cases, to increase it. Active or passive control procedures are of interest. The problems that we face here are considerable and encompass those related to the control of complex nonlinear systems and those related to the direct numerical simulation of turbulent ows. Our ai...
متن کاملTurbulent Flows: General Properties
Turbulence is ubiquitous in natural fluids: atmosphere, ocean, lakes, rivers, Earth’s interior, planetary atmospheres and their convective interiors, stars, and space gases (neutral and ionized). From a mathematical perspective, its essential behaviors arise because the equations of fluid dynamics are a nonlinear partial differential equation (PDE) system. From an accompanying physical perspect...

متن کاملStatistical Description of Turbulent Flows
This chapter focuses on the statistical approach to turbulence. On the one hand, it seeks to describe the evolution of mean and turbulent fields, and on the other, to highlight the transfer terms between these two fields. This splitting, introduced in 1883byReynolds, is not unique, nor themost satisfactory.Other flowdecompositions are given in Chaps. 8 and 9. Nevertheless, the Reynolds approach...
