Abstract

In this Letter we explore a new type of averaging in turbulence modelling, new types of characterization of the internal structure of turbulence (by two-point distribution function of fluid-particles), and consequences of the requirement that the Navier-Stokes equation and the governing equations of the models share a common structure of physical significance (Poisson structure). As a result we arrive at a turbulence model that includes the Reynolds-stress and LANS-α models, unifies them and extends them to models with an active advection. © 2004 Elsevier B.V.
