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 … WebJan 19, 2024 · Solutal Convection It is found that Rayleigh number for the case of overstability and stationary convection increases with increase in rotation parameter, as well as with intensity, solute parameter and decreases with increase in micropolar coefficients and medium permeability, for a fixed wave number, implying thereby the stabilizing effect …
WebWe present new experimental results relating to the growth and evolution of sea ice. These show, in particular, that brine initially remains trapped in the interstices of the sea ice, only draining into the underlying ocean once the depth of the sea-ice layer exceeds a critical value. A general theory for convection within mushy layers is applied to develop a … WebThe dissolution of minerals into water becomes signi cant in geomorphology, when the erosion rate is controlled by the hydrodynamics transport of the solute. Even in absence …
WebDec 27, 2016 · Convection is induced by heating the suspension from above, and at large solutal Rayleigh numbers (of the order of 107-108) convective spoke patterns form. We show that in the presence of a marginal inclination of the cell as small as 19mrad the isotropy of the spoke pattern is broken and the convective patterns tend to align in the … WebThe flows and instabilities induced by surface-tension or thermal-radiation forces, together with Other research topics include the study of the factors controlling defect generation diffusive instabilities, can each be studied and all have substantial practical as well as during growth from the melt of commercially important materials such as cadmium theoretical …
WebMay 15, 2024 · The relative motion during the solidification is induced by different flow phenomena, for example, equiaxed sedimentation, thermo-solutal convection or feeding flow. In this study it is dedicated to illustrate the delicate mechanism of macrosegregation during solidification with the presence of thermal-solutal convection.
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. new generation wellness irvine caWebDec 11, 2024 · Linear and weakly nonlinear stability analyses are performed to investigate the dissolution-driven convection induced by the sequestration of carbon dioxide in a perfectly impervious geological formation. ...
