Surface tension driven flow
Web'The additive and subtractive process used in in the making of my work results in a sedimentary layering, an abstracted geology of elements, in … WebA surface tension driven micropump proves to be a simple and attractive passive method to drive fluid flow in microdevices. We observed the appearance of a backward flow. Consideration of inertia of the fluid in the channel revealed that it alone is insufficient to explain the observed backward flow.

WebApr 30, 2012 · The method for simulation of surface-tension-driven interfacial flow with smoothed particle hydrodynamics is developed. The calculation of surface tension force is based on the interface reconstruction. The boundary particles for each fluid are detected dynamically. The position of the interface particles are specified in the middle of the ... WebDec 31, 2007 · Surface tension is defined as a cohesive molecular force acting on the surface of all liquids, which tends to force the solution to its smallest volume. The surface of the liquid, due to...
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). WebThis process is driven by the Marangoni stresses resulting from the formation of surface-active polyelectrolyte–surfactant complexes in solution and the salt arising from the release of counterions. ... of the drop to the three-phase contact line for those cases in which the concentration of the complexes dominates the surface tension ...
WebMar 1, 2024 · It was found that the surface tension driven flow was mainly determined by the temperature derivative and concentration derivative. Mukherjee et al [22] developed a three-dimensional model to study the heat transfer and fluid flow in additive manufacturing.
