Abstract
In this article, an entrance chamber was designed with new geometry for a vortex tube to continuously operate at low pressures. The air streams flow in opposite directions in the tube and the chamber was 3-D printed using a biodegradable plastic (polyacid lactic). The aim was to find a more appropriate chamber inlet geometry for continuous vortex tube and compressor operation in a low-pressure range. The experimental results showed that a tangential injection provided a greater difference in the hot/cold temperature difference and a better coefficient of performance (COP) for the same working conditions. The entrance diameters, which presented a better cold to inlet air temperature difference, were for 2 bar and 3 bar a value of 7 mm, and for 4 bar a value of 5.5 mm. These cooled airflows have different applications in commercial or industrial installations.
