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 … 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. irby street sporting goods facebook

WebAccording to the seminal theory by Sternling and Scriven [1], solutal Marangoni convection during mass transfer of surface-active solutes may occur as either oscillatory or stationary instability. With strong support of Manuel G. Velarde, a combined initiative of experimental works, in particular to mention those of Linde, Wierschem and coworkers, and theory has … WebConvective instabilities predominant in thin liquid films are due to surface-tension gradient-induced Marangoni convection. Bénard was the first to report regular patterns of vertical convection cells in non-evaporating pure liquid films heated from below, with a lateral length scale similar to the film height [30,31]. irby street florenceWebThe dissolution of minerals into water becomes signi cant in geomorphology, when the erosion rate is controlled by the hydrodynamics transport of the solute.
