Körfolyás

Körfolyás is a Hungarian noun that describes the process of circulating or moving in a closed loop. It derives from kör, meaning circle, and folyás, meaning flow. The term is used in everyday language as well as in various technical contexts to refer to the continuous movement of a substance through a defined circuit.

In physiology, the standard term for the circulation of blood is keringés; körfolyás can appear in descriptive or historical texts to convey the general idea of circulation but is less common in modern medical usage. In fluid dynamics and engineering, körfolyás refers to the circulation of liquids or gases within a system, such as the cooling water loop of equipment or larger-scale phenomena like oceanic and atmospheric circulation when discussed in broader terms.

In economics or social discourse, körfolyás may be used metaphorically to describe a circular flow of goods, services, and money. More specialized terminology in these fields often favors terms like körforgás or cirkuláció, depending on the context.

Key characteristics of körfolyás include a closed loop, continuous motion, and an energy source or driving force needed to sustain the flow. The flow can be laminar or turbulent, depending on factors such as viscosity, velocity, and the geometry of the system. Observing and modeling körfolyás typically involve measures such as flow rate, velocity, and density, with domain-specific concepts like cardiac output in physiology or Reynolds number in fluid dynamics.
