A new scaling property of turbulent flows.
A new scaling property of turbulent flows. Abstract We discuss a possible theoretical interpretation of the self scaling property of turbulent flows (Extended Self Similarity). Our interpretation predicts that, even in cases when ESS is not observed, a generalized self scaling, must be observed. This prediction is checked on a number of laboratory experiments and direct numerical simulations.
متن کاملControl 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...
