Boundary layer interaction in plume-based variable-viscosity thermal convection
Résumé : Nous avons mesuré la fréquence de formation de panaches dans une expérience de convection thermique à Pr >>1. Comme la viscosité du fluide utilisé varie fortement avec la température, les couches limites chaude et froide ont différentes épaisseurs et viscosités. Ceci entraîne des fréquences différentes pour ces couches. Il semblerait qu’il y ait une interaction directe entre les couche...
متن کاملPractical analytical solutions for benchmarking of 2-D and 3-D geodynamic Stokes problems with variable viscosity
Geodynamic modeling is often related with challenging computations involving solution of the Stokes and continuity equations under the condition of highly variable viscosity. Based on a new analytical approach we have developed particular analytical solutions for 2-D and 3-D incompressible Stokes flows with both linearly and exponentially variable viscosity. We demonstrate how these particular ...
متن کاملFree Convection Flow with Variable Viscosity Through Horizontal Channel Embedded in Porous Medium
Laminar free convection flow of viscous, incompressible fluid with variable viscosity and viscous dissipation through two horizontal parallel walls embedded in a porous medium is studied. Arrhenius model is used in which the variable viscosity is used to be decreasing exponentially with temperature. An approximation technique is defined to obtain the solution of the coupled non-linear equations...
متن کاملControl of Marangoni Convection in a Variable-Viscosity Fluid Layer with Deformable Surface
The effectiveness of a proportional feedback control to suppress the Marangoni instability in a variable-viscosity fluid layer with a deformable free upper surface is investigated. Viscosity variation and deformable free surface have destabilizing effects on the stability limit. The stability thresholds for the short-scale mode are strongly dependent on viscosity variation and controller gain w...
متن کاملNatural convection flow over an inclined flat plate with internal heat generation and variable viscosity
The present investigation deals with study of laminar natural convection flow of a viscous fluid over a semi-infinite flat plate inclined at a small angle to the horizontal with internal heat generation and variable viscosity. The dimensionless boundary layer equations are solved numerically for a negatively inclined plate using a very efficient marching order implicit finite difference scheme....
