We present a method for studying penetrative convection within the anelastic approximation. This method is then applied to two-dimensional numerical simulations of a convective region bounded below by a stable (radiative) region. Descending plumes penetrate into the stable layer, exciting gravity waves with a spectrum of frequencies limited by the ‘‘Brunt-Väisäla’’ frequency. The depth of penet...

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...

We numerically investigate the ability of ambient noise surface wave interferometry to invert for anelastic attenuation. Shorter correlation time windows leads to higher signal-to-noise ratio of empirical Green’s functions (EGF’s). We show, however, that it is necessary to correct for the window length and that this is especially important if short time windows are employed. Furthermore, we sho...

Anelastic convection at high Rayleigh number in a plane parallel layer with no slip boundaries is considered. Energy and entropy balance equations are derived, they used to develop scaling laws for the heat transport Reynolds number. The appearance of an structure consisting well-mixed uniform interior, bounded by thin layers jumps across them, makes it possible derive explicit forms these laws...

Extreme anelastic responses (stiffness greater than diamond and large amplification of damping) due to the presence of a negative stiffness phase have been observed in Zn80Al20-BaTiO3 composites not only near the tetragonalorthorhombic transformation temperatures of BaTiO3 anticipated by the classical Landau theory, but far below the Curie point of BaTiO3 which can be manipulated via specific a...

The low frequency anelastic properties of CDW compounds near the Peierls phase transition are studied in a forced sub-resonant pendulum suitable for delicate (TaSe,), I samples. The influence of measurement parameters such as frequency, oscillation amplitude, temperature rate and low temperature cycles, are obtained. The principal effects found are : the Peierls transition, a higher temperature...
