Solutal convection induced by dissolution

WebApr 15, 2024 · First, when a soluble body is plunged into quiescent water, the dissolution itself induces solutal convection. The flow creates dissolution patterns, the initial scale of which is set by the solutal Rayleigh-Bénard instability. Secondly, we report the emergence of a streamwise dissolution pattern at the surface of an initially flat soluble ... WebDissolution increases the density of the water and so can lead to downwelling convection, which, in turn, substantially increases the rate of dissolution of CO 2 at the water–CO 2 interface. This convective dissolution process has inspired a great deal of academic study over the last 10–15 years; indeed, this wealth of recent research is one of the primary …
