Surface tension driven flow
WebThe equations describing the dynamics of the surface-tension-driven flow include the continuity equation (i), the Navier-Stokes equations (2), a kinematic free- surface condition (3), a surface-tension boundary condition setting the normal pressure jump at the free surface (4) and the appropriate boundary conditions on velocity (5). WebApr 5, 2024 · Surface tension driven flows can be created or controlled passively i.e. without any external force or actively with applying a driving power. Let us briefly discuss here …

WebTime-dependent potential flows of a liquid with a free surface are considered, with surface tension the force that drives them. Two types of configuration are analyzed, in each of which the flow and the free surface are self-similar at all times. One is … WebSurface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water …
WebOct 27, 2015 · Cellular structures appeared on the paint surface, induced by surface tension-driven flows due to solvent concentration variations. For thin films (<500 µm), the patterns disappeared in a few ... Webat the water’s surface will be driven along the maze by the disruption of the water’s surface tension. Make sure students observe what happens to the water at the bottom of the tray …
WebThe solution can develop finite-time singularities, which are regularised by surface tension over a short lengthscale. General inner solutions are found for the neighbourhoods of such singularities and matched with the solution of the outer hyperbolic problem.
WebIn general, surface tension σ de- pends on both the temperature and chemical composition at the interface; consequently, Marangoni flows may be generated by gradients in either …
