This is an important area of research in this field, and a major goal of the modern theory of turbulence is to understand what is universal in the inertial range, and how to deduce intermittency properties from the Navier-Stokes equations, i.e. from first principles.
Meneveau also has performed groundbreaking research on understanding several multiscale aspects of turbulence. As part of his doctoral work at Yale in the late 1980s, Meneveau and his advisor Prof. K. R. Sreenivasan established the fractal and multifractal theory for turbulent flows and confirmed the theory using experiments. Interfaces in ...
Turbulence remains the major unsolved domain of fluid mechanics. Theodorsen identified the main turbulence-creating terms in the equations of motion as (q x curl q . curl curl q); he showed that two-dimensional turbulence cannot exist; that vortex lines stretching and bending is the important mechanism and ingredient of turbulence.
In fluid dynamics, turbulence modeling is the construction and use of a mathematical model to predict the effects of turbulence. Turbulent flows are commonplace in most real-life scenarios. In spite of decades of research, there is no analytical theory to predict the evolution of these turbulent flows.
Victor S. L'vov (Russian: Виктор Сергеевич Львов) is a Russian-Israeli physicist most known for his contributions to the advanced theories and applications of wave and hydrodynamic turbulence, as well as nonlinear phenomena in various physical systems, including plasma, superfluids, classical environmental flows, and solid states.
A new study suggests Vincent van Gogh showed a deep, intuitive understanding of the mathematical structure of turbulence in his painting “The Starry Night.”
Schematic illustration of production, energy cascade and dissipation in the energy spectrum of turbulence. The largest motions, or eddies, of turbulence contain most of the kinetic energy, whereas the smallest eddies are responsible for the viscous dissipation of turbulence kinetic energy. Kolmogorov hypothesized that when these scales are well ...
Lumley received the 1990 Fluid Dynamics Prize of American Physical Society, "For his outstanding contributions to the understanding of turbulent flow, in particular, the fundamental structure of turbulent shear flows, the effects of drag-reducing additives, and his widely recognized contributions to the statistical theory of turbulence, and for his personal and intellectual leadership in the ...
