چکیده
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. These given terms number, Prandtl bottom top temperature ratio, which also measures how much density varies layer. boundary examined found be very different, unlike Boussinesq case. Elucidating plays crucial part determining Physical arguments governing presented, concentrating on case so that vary little even though there may substantial variations whole Different found, depending whether viscous dissipation primarily or bulk. cases both low Numerical simulations no-slip anelastic up $10^7$ have been performed our theoretical predictions compared numerical results.

Anelastic convection-driven dynamo benchmarks
Benchmark solutions for fully nonlinear anelastic compressible convection and dynamo action in a rotating spherical shell are proposed. Three benchmarks are specified. The first is a purely hydrodynamic case, which is steady in a uniformly drifting frame. The second is a self-excited saturated dynamo solution, also steady in a drifting frame. The third is again a self-excited dynamo but is unst...
متن کاملA Steady Mixing Flow with No-slip Boundaries
A steady mixing (even Bernoulli) smooth volume-preserving vector field in a bounded container in R3 with smooth no-slip boundary is constructed. An interesting feature is that it is structurally stable in the class of C3 volumepreserving vector fields on the given domain of R3 with smooth no-slip boundary, thus if one could think how to drive it then it would be physically realisable. It is poi...
متن کاملPenetrative Convection within the Anelastic Approximation
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...
متن کاملeffects of slip boundaries on mixed convection of al2o3-water nanofluid in microcavity
mixed convection of al 2 o 3 -water nanofluid in a square microcavity is investigated numerically. governing equations are discretized and solved using the finite volume method and simpler algorithm. the knudsen number is selected between 0.001 and 0.1 to consider slip velocity and the jump temperature boundary conditions. results showed that nusselt number is a function of richardson number, k...
متن کاملStructure of bifurcated solutions of two-dimensional infinite Prandtl number convection with no-slip boundary conditions
We consider the two-dimensional infinite Prandtl number convection problem with no-slip boundary conditions. The existence of a bifurcation from the trivial solution to an attractor ΣR was proved by Park [15]. The no-stress case has been examined in [16]. We prove in this paper that the bifurcated attractor ΣR consists of only one cycle of steady state solutions and it is homeomorphic to S. By ...
