Seawater flows tangentially along the membrane, creating a boundary layer on the membrane surface. Membranes have to cleaned typically when: - normalized permeate flow varies by 10-15% - normalized feed pressure varies by 10-15%.
Whether they can break through will depend on the thickness of the mechanical boundary layer (mbl), or lithosphere. The mbl is thin at ocean ridges, so plumes can easily break through, and the energy converted to extensive melting and formation of an ocean plateau.

The boundary layer consists of a mixed layer that is stirred by solar heating of the surface and convection of warm moist air that pops up sporadically from place-to-place and time-to-time, and, as a result, mixes the air within the boundary layer.
Typically, the best way to capture effects in the boundary layer is by accommodating higher number of cells in the direction normal to the fluid flow. For mainstream flow, i wouldn’t expect gradients to change much. Hence i recommend reducing the mesh intensity in the flow direction.
Equilibrium convection is generally interpreted as indicating that the convection is in equilibrium.

In other words, the boundary layer is a region of very large velocity gradients. According to newton’s shear-stress law, which states that the shear stress is proportional to the velocity gradient, the local shear stress can be very large within the boundary layer. As a result, the skin-friction drag force exerted on the body is not negligible, contrary.

This sublayer, known as the planetary boundary layer, is that region of the atmosphere in which the surface influences temperature, moisture, and wind velocity through the turbulent transfer of mass. As a result of surface friction, winds in the planetary boundary layer are usually weaker than above and tend to blow toward areas of low pressure.

Boundary-layer theory can be applied to the flow about an airfoil in two ways. First, the boundary-layer development can be determined for a given potential flow velocity distribution. Second, the potential-flow field, or at least some of its properties, can be determined for a given boundary-layer development.
Thermal turbulence is well known as a potent means to convey heat across space by a moving fluid. The existence of the boundary layers near the plates, however, bottlenecks its heat-exchange capability.

Prandtl’s thin boundary layer theory is the huge breakthrough in the fluid mechanics and aerodynamics. It is amazing that a thin layer is actually responsible for substantial drag on a body while the flow outside that layer has no significance on the drag.
The boundary layer attracts and drags successive layers of fluid molecules into layered flows of parallel streams. This is the simple principle of viscous drag and in the disc pump it is a powerful dynamic force that “pulls” the fluid through the pump in a smooth laminar, non turbulent flow.
