The Cassini missions have identified the tiger stripes on Enceladus as source of both thermal emission and plume jets. hot spots in are highly localized, plumes suggest active hydrothermal processes within subglacial ocean Enceladus. However, understanding mechanism responsible for heat anomalies remains a challenge. About 60 y ago, geoscientist George Veronis proposed model cold water oceans, along with classical notion 1/3 scaling relationship between vertical transfer Rayleigh number ( Ra...
This paper investigates the linear and nonlinear dynamics of two-dimensional penetrative convection subjected to radiative volumetric thermal forcing, focusing on ice-covered freshwater systems. Linear stability analysis reveals how critical wavenumbers $k_c$ Rayleigh numbers $Ra_c$ are influenced by attenuation lengths incoming heat flux. In this configuration, system easily becomes unstable with a small , which is two decades smaller than that classical Rayleigh–Bénard problem, typically...
This paper investigates heat transport in penetrative convection with a marginally stable temporal-horizontal-averaged field or background field. Assuming that the is steady and stabilised by nonlinear perturbation terms, we obtain an eigenvalue problem unknown temperature $\tau$ truncating terms. Using piecewise profile for , derived analytical scaling law as $Ra\rightarrow \infty$ : $Nu=(1/8)(1-T_M)^{5/3}Ra^{1/3}$ ( $Nu$ Nusselt number; $Ra$ Rayleigh number $T_M$ corresponds to at which...
Abstract An unstably stratified flow entering into a stably is referred to as penetrative convection, which crucial many physical processes and has been thought of key factor for extreme weather conditions. Past theoretical, numerical, experimental studies on convection are reviewed, along with field providing insights turbulence modeling. The factors that initiate including internal heat sources, nonlinear constitutive relationships, centrifugal forces other complicated summarized....
Abstract Rayleigh-Bénard-Marangoni instability in a bilayer system of self-rewetting fluid overlying porous medium is investigated. The upper surface the layer assumed non-deformable and constant temperature gradient imposed. Unlike previous works, considered this paper, whose tension quadratic function temperature. As result, it would reinforce or suppress caused by buoyancy different scenarios. Thorough study carried out influence depth ratio h , Rayleigh number Ra Biot Bi on discussed. It...
