Statistical Averaging in Variable Density Fluid Turbulent Motion, with first (mean) and second order moments. Two different formulations will be mainly considered, referring to mean mass-conservative and non conservative evolutions. It is not intended for extensive and detailed presentations of the different formalisms — using either the classical formulation of

Some Basic Variable Density Mechanisms in Turbulent Flows,t flows different from the incompressible ones..The equation governing the instantaneous vorticity is first derived in the general case: fluid with variable density and nonconstant physical properties. Then, new vorticity generation mechanisms, as compared with the constant density situation, are di

Relative Behaviour of Velocity and Scalar Structure Functions in Turbulent Flows, turbulent flows. The assumptions which underpin this framework are only likely to be validated at very large Reynolds numbers and for relatively homogeneous and isotropic flows. These conditions are unlikely to apply in the laboratory. The major emphasis is on the likely dependence of second-order

The Structure of Some Variable-Density Low-Speed Shear Flows,able-density flows are best accounted for as seen from their vorticity dynamics. The baroclinic torque, connecting misaligned pressure and density gradients, reorganizes the vorticity field according to the fluid inertia. It is introduced after a short literature survey. Then the particular cases of

First-Order Modeling,ion and discussion of prediction methods for turbulent flows, based on statistical — or Reynolds — averaged Navier-Stokes equations (RANS). Then, the incidence of density changes and the incorporation of variable-density and compressibility effects in first-order closure models are analyzed with res
