What is the air pattern produced by a vortex tube called?

The air pattern produced by a vortex tube is referred to as a "swirl." A vortex tube generates this swirling motion by creating a differential temperature effect within the tube, where the air is separated into hot and cold streams through centrifugal force. The design and function of a vortex tube allow the air to swirl around the core of the tube, leading to efficient separation of temperature.

In the context of fluid dynamics, "swirl" specifically describes the rotational movement of the fluid in a cylindrical manner, which aligns perfectly with how the vortex tube operates. Understanding this air pattern is crucial for HVAC professionals, as it relates to the principles of thermal dynamics and cooling efficiencies utilized in various applications.
