F15D FLUID DYNAMICS, i.e. METHODS OR MEANS FOR INFLUENCING THE FLOW OF GASES OR LIQUIDS
Introduced: September 1968
Classification Context
- Section:
- MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
- Class:
- FLUID-PRESSURE ACTUATORS; HYDRAULICS OR PNEUMATICS IN GENERAL
- Subclass:
- FLUID DYNAMICS, i.e. METHODS OR MEANS FOR INFLUENCING THE FLOW OF GASES OR LIQUIDS
Description
This subclass encompasses methods and apparatus for controlling, directing, and modifying the flow characteristics of gases and liquids in practical applications. It covers devices such as diffusers, nozzles, flow control valves, and systems that use fluid dynamics principles to achieve desired flow patterns, pressure distributions, or velocity profiles. The classification includes both active and passive flow control techniques, including swirl generators, flow straighteners, and jet deflection mechanisms. F15D excludes general fluid mechanics theory and focuses on engineered means for practical flow manipulation in hydraulic, pneumatic, and general fluid systems.
