Solutal driven flow is studied for a binary solution submitted to solvent evaporation at the upper free surface. Evaporation induces an increase in solute concentration close surface and solutal gradients may induce convective by buoyancy and/or tension. This problem numerically, using several assumptions deduced from previous experiments on polymer solutions. The stability of system investigated as function Rayleigh Marangoni numbers, evaporative flux Schmidt number. sensitivity thresholds...

ABSTRACT This article presents numerical results using a new finite-volume scheme on unstructured grids for the incompressible Navier-Stokes equations. The discrete unknowns are components of velocity, pressure, and temperature, colocated at centers control volumes. is stabilized an original method leading to local redistributions fluid mass, which simultaneously yields kinetic energy convergence scheme. Different comparisons with literature (2-D 3-D lid-driven cavity, backward-facing step,...

In order to increase the accuracy and stability of a scheme dedicated approximation diffusion operators on any type grids, we propose method which locally reduces curvature discrete solution where loss monotony is observed. The shown fulfill variational formulation, thanks use Lagrange multipliers. We can then show its convergence continuous problem, an error estimate derived. A numerical method, based Uzawa's algorithm, provide accurate stable approximate solutions various problems....

Linear stability analyses for two-dimensional natural convection in horizontal air-filled annuli are performed three-dimensional perturbations and radius ratios the range 1.2⩽R⩽3. Flow transitions from moderate to large-gap annuli, which have not been reported before, thoroughly investigated. As a result, diagrams obtained finite infinite length annuli. The leading disturbances threshold values found agree well with experimental data numerical solutions. Three-dimensional simulations were...

Abstract We describe here a collocated finite volume scheme that was recently developed for the numerical simulation of incompressible Navier–Stokes equations on unstructured meshes, in two or three space dimensions. recall its convergence case linear Stokes equations, and we prove theorem under Boussinesq hypothesis. then present several studies. A comparison between cluster‐type stabilization technique more classical Brezzi–Pitkäranta method is performed, properties are presented both...

In the usual models of thermocapillary flows, a vorticity singularity occurs at contact free surface–solid boundaries. The steady axisymmetric hydrodynamics side-heated liquid bridge molten metal is addressed here for its sensitivity to size δ length scale explicitly introduced regularize problem. By linear stability analysis various stable states are predicted: already known which reflection-symmetric about mid-plane, but also others do not possess this property. thresholds in Ma associated...
