Numerical Study of the Eulerian Correlations and Lagrangian Velocity in Stably Stratified Homogeneous Turbulence
- 1 Laboratory of Fluid Mechanics, Department of Physics, Faculty of Science of Tunis, University of Tunis El Manar, Tunisia
This study is based on a linear analysis in spectral space. To express the correlation double speed using Lagrangian Dual Eulerian correlations, we use the Corrsin assumption and then we compute the components of the tensor of the square displacements means. We begin by rewriting the basic linear equations governing the evolution of double correlations spectra. Subsequently, we analyze the numerical results.
