A Reduced Model for Salt-Finger Convection in the Small Diffusivity Ratio Limit
A simple model of nonlinear salt-finger convection in two dimensions is derived and studied. The model is valid in the limit of a small solute to heat diffusivity ratio and a large density ratio, which is relevant to both oceanographic and astrophysical applications. Two limits distinguished by the magnitude of the Schmidt number are found. For order one Schmidt numbers, appropriate for astroph...
متن کاملSalt-fingering convection in the small diffusivity ratio limit
Doubly diffusive processes play a fundamental role in many physical phenomena of substantial geophysical and astrophysical importance. Despite much research basic questions, e.g. how primary and secondary instabilities saturate and how mean fields are generated, remain unresolved. In the salt-finger regime, we use a systematic asymptotic procedure to reduce the primitive equations to a prognost...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
The Keller-Segel model with small diffusivity
We study the classical model for chemotaxis, the so-called Keller-Segel model, which is a drift-diffusion equation for the cell density coupled with an elliptic equation describing the evolution of the chemoattractant. We investigate the case of small cell diffusivity and, in particular, the hyperbolic limit of the system as the diffusion coefficient goes to zero. Considering a model where the ...
متن کاملLyapunov exponents for small aspect ratio Rayleigh-Bénard convection.
Leading order Lyapunov exponents and their corresponding eigenvectors have been computed numerically for small aspect ratio, three-dimensional Rayleigh-Benard convection cells with no-slip boundary conditions. The parameters are the same as those used by Ahlers and Behringer [Phys. Rev. Lett. 40, 712 (1978)] and Gollub and Benson [J. Fluid Mech. 100, 449 (1980)] in their work on a periodic time...
