Generalizing the Boussinesq Approximation to Stratified Compressible Flow
The simplifications required to apply the Boussinesq approximation to compressible flow are compared with those in an incompressible fluid. The larger degree of approximation required to describe mass conservation in a stratified compressible fluid with the Boussinesq continuity equation has led to the development of several different sets of “anelastic” equations that may be regarded as genera...
متن کاملVisualization of Rayleigh–Taylor flows from Boussinesq approximation to fully compressible Navier–Stokes model
Visualizations of Rayleigh–Taylor turbulent mixing layers are presented. Three Navier–Stokes models are used: Boussinesq, anelastic and fully compressible. Isosurfaces and slices of concentration, vorticity, Q-criterion, turbulent kinetic energy, local Taylor-microscale Reynolds number, dissipation, pressure and temperature are displayed. This gives an overall picture of the Rayleigh–Taylor flo...
متن کاملThe Oberbeck-Boussinesq approximation in critical spaces
In this paper we study the validity of the so-called Oberbeck-Boussinesq approximation for compressible viscous perfect gases in the whole three-dimensional space. Both the cases of fluids with positive heat conductivity and zero conductivity are considered. For small perturbations of a constant equilibrium, we establish the global existence of unique strong solutions in a critical regularity f...
متن کاملDispersive Estimates for the Stably Stratified Boussinesq Equations
We consider the initial value problem for the 3D Boussinesq equations for stably stratified fluids without the rotational effect. We establish the sharp dispersive estimate for the linear propagator related to the stable stratification. As an application, we give the explicit relation between the size of initial data and the buoyancy frequency which ensures the unique existence of global soluti...
متن کاملStability of Unstably Stratified Shear Flow in a Channel Under Non-Boussinesq Conditions
We investigate the linear stability of unstably strati ed Poiseuille ow between two horizontal parallel plates under non-Boussinesq conditions. It is shown, that Squire's transformation can be used to reduce the three-dimensional stability problem to an equivalent two-dimensional one. The eigenvalue problem, consisting of the generalized Orr-Sommerfeld equations, is solved numerically using an ...
