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.
