Mixing Of A Starting Turbulent Jet In Homogeneous And Isotropic Turbulence

Proceedings of the International Symposium on the Application of Laser and Imaging Techniques to Fluid Mechanics
The mixing of a starting turbulent jet, injected with an injection velocity of U = 18.8 m/s from a tube with a diameter of D = 4mm (Reynolds number Re = 4800, characteristic time scale t* = D/U = 0.21 ms at the nozzle exit), is experimentally investigated in the presence of homogenous and isotropic turbulence (HIT) using Planar Laser-induced ...

The integral scale in homogeneous isotropic turbulence

Journal of Fluid Mechanics, 2002
A simple spectral model is used to examine what is required to determine the energy and integral scale in homogeneous isotropic turbulence. The problem is that these are determined in part by the largest scales of the turbulence which are either not simulated at all by DNS or experiments, or cannot be estimated because of an insufficient ...

Geometry and statistics in homogeneous isotropic turbulence

2007
In this paper, we consider a phenomenological model, incorporating the main features of hydrodynamic fluid turbulence, aimed at predicting the structure of the velocity gradient tensor, M, coarse-grained at a spatial scale r. This model (M. Chertkov, A. Pumir and B.I. Shraiman, Phys. Fluids 11, 2394 (1999)) is formulated as a set of stochastic ordinary

Inequalities in isotropic homogeneous turbulence theory

Journal of Mathematical Physics, 1981
It is postulated that the energy spectrum function is the Laplace transform of a nonnegative distribution φ. The principal physical parameters in the longitudinal correlation function are then expressed in terms of φ integrals and interrelated by Hölder inequalities, to yield experimentally confirmed results like Lp⩾1.825λ.
