Solutal convection induced by dissolution

WebOur results complete our previous numerical work [J. Philippi et al., "Solutal convection induced by dissolution," Phys. Rev. Fluids 4, 103801 (2024)] ... We show that the criterion … 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.

WebMay 21, 2024 · Abstract. We combine modeling and measurements to investigate the dynamics of convective carbon dioxide (CO 2) dissolution in a pressure-volume-temperature cell, extending a recent study by Wen et al. (J. Fluid Mech., vol. 854,2024, pp. 56-87) at low-pressure under ideal-gas conditions to high-pressure and real-gas conditions.Pressure … 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.
