Separation
Separation is a phenomenon that occurs when a fluid separates into distinct regions due to a difference in pressure or density. This can happen when a fluid is forced to flow through a constriction, or when two immiscible fluids are placed in contact with each other.
The point at which the fluid separates is called the separating surface. The velocity of the fluid in the core region is higher than the velocity of the fluid in the boundary layer. This creates a pressure difference across the surface, which causes the fluid to separate.
As the fluid moves away from the constriction or into the two immiscible fluids, it experiences a change in velocity and pressure. This creates a force that pulls the fluid outward. The rate at which the fluid separates is determined by the properties of the fluid, the geometry of the flow, and the pressure difference.
Examples:
When a water bottle is filled to the brim, the water at the top of the bottle separates from the water in the bottom of the bottle.
When a soap bubble is blown, the soap film separates from the water vapor in the bubble.
When a fluid is forced through a constricted pipe, the fluid separates into distinct layers
