WebThe most common boundary that comes upon in confined fluid flow problems is the wall of the conduit. The appropriate requirement is called the no-slip boundary condition, … WebThe no-slip boundary condition v (0) = 0 thus pertains to the tangential velocity of the electron fluid, while A, proportional to the tangential electric field, is actually continuous across the surface. This rule has the advantage of not needing a dimensional parameter (apart from the bulk viscosity fixed from the bulk behaviour).
