Study of a Vortex tube

DESCRIPTION

The Vortex or whirling tube is an original system which was invented by the French physicist Georges Ranques, and patented in France.

It does not include any moving parts and it can separate, with variable proportions, one compressed gas stream (TE) temperature in two gas streams one with the TC>TE temperature (hot stream) and the other with the TF<TE temperature (cold stream).

TECHNICAL SPECIFICATIONS

• Measurement of temperatures by means of Pt 100 Ω probes
• Measurement of air flow by means of class 1,25 float flow meters
• Measurement of inlet air pressure by means a Bourdon tube manometer : Ø 100 mm, class 1.6
• Digital temperature indicator, probe selection by means of a fast connecting system

PEDAGOGIC APPLICATIONS

Theoretical examination of the Vortex tube operating principle
Qualitative study
Qualitative study – performance curves

- Temperature deviation between the hot side and the cold part of the flow

- Temperature deviation between the cold side and the cold part of the flow

- = f (pressure) With a constant cold air flow, with a constant hot air flow, with a constant
