In this first part we propose and analyse a model for the study of two-dimensional incompressible Navier–Stokes equations with a temperature-dependent viscosity. The flow is supposed in a mixed convection regime and considers an outflow region, lea

In this second part, we analyse the associated discrete problem arising from a conforming finite element method formulation of the mathematical model presented in the first part. Thus, existence and uniqueness of the discrete solution when using smal

Our aim here is to study the thermal diusion phenomenon in a forced convective flow. A system of nonlinear parabolic equations governs the evolution of the mass fractions in multicomponent mixtures. Some existence and uniqueness results are given und

A numerical study of a 2D jet, confined in a heated or nonheated “horse shoe” cavity containing a bluff body is presented. Over critical conditions, this system exhibits self-sustained oscillations with well defined saturated amplitude and freque

Resume Nous etudions les auto-oscillations d'un jet plan se developpant dans une cavite contenant un obstacle. Au-dela du seuil primaire d'instabilite, les frequences d'oscillation du jet sont uniquement definies par des parametres geometriques, les

Hydrodynamic instabilities in wavy channels and their effect on the convective heat transfer are investigated using both linear stability analysis and integration of the time dependent Navier–Stokes and energy equations. The linear stability of the

International audience; We present the results of a chemometric analysis in the mid and near-infrared range for a gas mixture, with a composition close to that of natural gas. Different multivariate regression methods, i.e. principal component regres

International audience; The dynamic development of a laminar flow in a two-dimensional symmetric wavy channel isstudied numerically by numerical integration of the unsteady NavierStokes equations. It is shownthat beyond a critical Reynolds number t
