Solutal convection induced by dissolution
WebNote, however, that the here-studied convection driven by thermal gradients will be superimposed by solutal convection in an actual growth experiment. Due to the presumably faster dissolution in the upper zone, the density of the solute-containing fluid there will likely increase faster compared to the density of the fluid in the growth zone. WebThe dissolution of minerals into water becomes significant in geomorphology when the erosion rate is controlled by the hydrodynamic transport of the solute. Even in the …

It was found that the solutal Marangoni flow was very strong during the solidification of the steel melt with ... The jet vortices induced by the Q-criterion are investigated using the LBM model. The Q ... WebFIG. 1. (a) Shadowgraph image of solutal convective flow. A salt block is put in contact with fresh water and the image is taken 1.25 s after the contact. A graduation corresponds to 1 …
WebWe also revisit the scaling behavior of Sherwood number (Sh) with Rayleigh number (Ra), which has been under debate for porous-media convection. Our measurements from the solutal convection in the range 1500≲Ra≲135000 show that the classical linear scaling Sh ∼ Ra is attained asymptotically for the constant-concentration case. WebNonlinear solutal convection in a thin liquid layer driven by surface-tension gradients is studied. This effect is referred to as the Marangoni effect. The adsorbing ability of the upper surface is described by the Gibbs adsorption equation. The present analysis is based on the amplitude method, which allows for finite amplitude disturbances.
WebFeb 17, 2014 · We numerically characterize the temporal regimes for solutal convection from almost first contact to high dissolved solute ... D. 2011 Upscaling studies of … WebThe results show that mechanical dispersion, which was ignored before, plays an important role in quantifying solutal convection in porous media. Since dispersivity generally increases with the scale of observations, knowledge obtained from the counter-intuitive results can be applied to predict mass transfer in large-scale applications such as CO₂ convective …
WebThrough several complementary experiments, an investigation of the bulk and interfacial flows that emerged during the coalescence of two water-in-oil droplets with asymmetric compositional properties was performed. By adding surfactant to one of the coalescing droplets and leaving the other surfactant-free, a strong interfacial tension gradient (i.e., …

We apply the scaling laws previously established to the case of real dissolving minerals. We find a constant value of the Rayleigh number during the quasistationary regime, showing that the structure of the boundary layer is well controlled by the solutal convection. flashback boutiqueWebSolutal convection induced by dissolution Author: Julien Philippi1, Michael Berhanu1, Julien Derr1 and Sylvain Courrech du Pont1 Created Date: 4/18/2024 10:43:37 AM ... flashback blessed ink
