Field Theory and the Phenomenon of Turbulence
نویسنده
چکیده
We study the phenomenon of turbulence from the point of view of statistical physics. We discuss what makes the turbulent states different from the thermodynamic equilibrium and give the turbulent analog of the partition function. Then, using the soluble theory of turbulence of waves as an example, we construct the turbulent action and show how one can compute the turbulent correlation functions pertur-batively thus developing the turbulent Feynman diagrams. And at last, we discuss which part of what we learnt from the turbulence of waves can be used in other types of turbulence, in particular, the hydrodynamic turbulence of fluids. This paper is based on the talk delivered at SMQFT (1993) conference at the University of Southern California.

شبیهسازی عددی شکست موج تنها بر روی ساحل شیبدار به روش هیدرودینامیک ذرات هموار نسبتاً تراکمپذیر
In this article, a numerical meshless method called Weakly Compressible Smoothed Particle Hydrodynamic (WCSPH) is used to simulate the solitary wave breaking process on the beach. The present model is a two dimensional model that considers the fluid weakly compressibility. This model solves the viscous fluid equations to obtain velocity field and density and solves the equation of state to obta...
متن کاملModeling Tax Evasion in Value Added Tax, A Game Theory Approach
Taxes make up the bulk of any government revenue and provide a sustainable source of revenue. In recent years, the main focus of the tax reform program, in almost all countries of the world, has been on VAT. But a major problem in the effective implementation of VAT, which is a nascent tax base in countries, is the phenomenon of tax evasion. Therefore, one of the most basic steps in preventing ...
متن کاملFlow Field Characteristics of an Aerospike Nozzle Using Different Turbulence Models
To improve the calculation of the flow properties of an aerospike nozzle, different turbulence models were investigated in this study. The primary shape of the nozzle plug is determined through utilizing an approximate method. The flow field is, then, simulated using the Navier-Stokes equations for compressible flows. The commercial computational fluid dynamics code Fluent is used to simulate t...
متن کاملA Study on Scientific Community of Social Sciences Professors Relying on Bourdieu’s Field Theory
Since Science is a social phenomenon, active groups of actors in a scientific field are called scientific community. The relationship between scientific capital and scientific community constructs the subject matter of current paper which is addressed through Pierre Bourdieu’s field theory and his theory of Habitus. Scientific community of sociology in various universities of Tehran were select...
متن کاملThe Mean Field Theories of Magnetism and Turbulence
In the last few decades a series of experiments have revealed that turbulence is a cooperative and critical phenomenon showing a continuous phase change with the critical Reynolds number at its onset. However, the applications of phase transition models, such as the Mean Field Theory (MFT), the Heisenberg model, the XY model, etc. to turbulence, have not been realized so far. Now, in this artic...
