Anisotropy of the Lundgren-Townsend model of fine-scale turbulence
نویسندگان
چکیده
The effect of a statistically anisotropic distribution of stretched vortices in the LundgrenTownsend model of the fine-scale structure of homogeneous turbulence is considered. Lundgren’s argument that anisotropy does not affect the three-dimensional energy spectrum is confirmed. Examples of velocity derivative moments and one-dimensional vorticity spectra are worked out for the case of an axisymmetric probability distribution. It is found that scaling of three-dimensional vorticity spectra may not be visible in the one-dimensional spectra.

Pressure spectra for vortex models of fine-scale homogeneous turbulence
Pressure spectra at large wave numbers are calculated for Lundgren-Townsend vortex models of the fine scales of homogeneous turbulence. Specific results are given for the Burgers vortex and also for the Lundgren-strained spiral vortex. For the latter case, it is fqund that the contribution to the shell-summed spectrum produced by the interaction between the axisymmetric and nonaxisymmetric comp...
متن کاملOn the Lundgren-Townsend model of turbulent fine scales
The strained-spiral vortex model of turbulent fines scales given by Lundgren [Phys. Fluids 25, 2193 ( 1982)] is used to calculate vorticity and velocity-derivative moments for homogeneous isotropic turbulence. A specific form of the relaxing spiral vortex is proposed modeled by a rolling-up vortex layer embedded in a background containing opposite signed vorticity and with zero total circulatio...
متن کاملExact Solutions for Modified Burgers Vortex
The vortex stretching process is relevant to energy transport at various scales in turbulent flow and in vortex reconnection. For these, reasons, exact solutions for vortex flow are useful. Robinson and Saffman [1] examined the Burgers vortex solution and found closed form steady solutions for special parameter values. Unsteady 2D Burgers vortex solutions have been used to model the spanwise st...
متن کاملInternal combustion engines in cylinder flow simulation improvement using nonlinear k-ε turbulence models
The purpose of this paper is to studying nonlinear k-ε turbulence models and its advantages in internal combustion engines, since the standard k-ε model is incapable of representing the anisotropy of turbulence intensities and fails to express the Reynolds stresses adequately in rotating flows. Therefore, this model is not only incapable of expressing the anisotropy of turbulence in an engine c...
متن کاملCalculation of velocity structure functions for vortex models of isotropic turbulence
Velocity structure functions (up 82up) m are calculated for vortex models of isotropic turbulence. An integral operator is introduced which defines an isotropic two-point field from a volume-orientation average for a specific solution of the Navier–Stokes equations. Applying this to positive integer powers of the longitudinal velocity difference then gives explicit formulas for (up 82up) m as a...
