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). 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. WebThe leading edge of the flowing blood is the triple point where the blood, the material surface, and a stationary gas orfluid meet. The movement of the triple point, i.e., the advancing front of the flow, is driven by surface tension, resisted by viscous shear stress, and balanced by the inertial force (-mass x acceleration). genshin impact gta 5 mods
