We present an overview of the current status in the development of a two-point spectral closure model for turbulent flows, known as the local wavenumber (LWN) model. The model …
This paper presents a method for accurate and efficient computations on scalar, vector and tensor fields in three-dimensional spherical polar coordinates. The method uses spin …

A nonlinear spectral model in terms of spherically averaged descriptors is derived for the prediction of homogeneous turbulence dynamics in the presence of arbitrary mean-velocity …
We present a study of buoyancy-driven variable-density homogeneous turbulence, using a two-point spectral closure model. We compute the time-evolution of the spectral distribution …

We show how two-point turbulence models based on triadic closures, initially developed for homogeneous isotropic turbulence, can be applied to anisotropic turbulent flows. Efficient …
The purpose of this work is to study the anisotropic properties of the inertial range of Rayleigh-Taylor and unstably stratified homogeneous (USH) turbulence. More precisely, we …

We consider freely decaying homogeneous anisotropic turbulence whose energy spectrum E (k) at k→ 0 is given by E (k)= C k 2+ o (k 2) at an initial instant, where k is the wave number …
This article, or essay, addresses the anisotropic structure and the dynamics of quasi- homogeneous, incompressible turbulence. Modal projection and expansions in terms of …

A computational tool for the anisotropic time-evolution of the spectral velocity correlation tensor is presented. We operate in the linear, rapid distortion limit of the mean-field-coupled …
