In fluid dynamics, a secondary flow is a relatively minor flow superimposed on the primary flow, where the primary flow usually matches very closely the flow pattern predicted using simple analytical techniques and assuming the fluid is inviscid. (An inviscid fluid is a theoretical fluid having zero viscosity.)
The primary flow of a fluid, particularly in the majority of the flow field remote from solid surfaces immersed in the fluid, is usually very similar to what would be predicted using the basic principles of physics, and assuming the fluid is inviscid. However, in real flow situations, there are regions in the flow field where the flow is significantly different in both speed and direction to what is predicted for an inviscid fluid using simple analytical techniques. The flow in these regions is the secondary flow. These regions are usually in the vicinity of the boundary of the fluid adjacent to solid surfaces where viscous forces are at work, such as in the boundary layer.

What are the three different types of cosumers?
The three different types of consumers are primary consumers, secondary consumers, and tertiary consumers. Primary consumers, often herbivores, directly consume producers (plants). Secondary consumers are carnivores that eat primary consumers, while tertiary consumers are top predators that feed on secondary consumers. This hierarchy illustrates the flow of energy through an ecosystem.

Can a generic term not be protected under trademark law unless it acquires a secondary meaning?
Yes, that is correct. A generic term, which refers to the common name or category of a product or service, cannot be protected under trademark law unless it acquires a secondary meaning. Secondary meaning is when consumers associate the term with a specific source or brand rather than its generic meaning.
