sekundäärikierrostens

Sekundäärikierrostens refers to the secondary circulation within a system, often used in the context of fluid dynamics or thermodynamics. This secondary circulation is distinct from the primary flow path and arises due to various factors such as viscous effects, temperature gradients, or pressure differences. In many engineering applications, understanding and controlling secondary circulation is crucial for optimizing performance and efficiency. For example, in heat exchangers, secondary flows can enhance heat transfer rates by promoting mixing of fluids. Conversely, in rotating machinery like turbines or pumps, unwanted secondary flows can lead to increased losses and reduced efficiency. The formation and behavior of secondary circulation are typically analyzed using computational fluid dynamics (CFD) simulations or experimental measurements. Factors influencing secondary circulation include the geometry of the flow path, the properties of the fluid, and the operating conditions. Managing secondary flows often involves design modifications to the system or flow conditioners to redirect or suppress these secondary movements. The term is less common in everyday language and is primarily encountered in specialized technical fields.
