In view of the wide application of vortex tube (VOTU) in the market, and in order to enhance the capability of VOTU in the higher inlet pressure, three-dimensional numerical simulations were performed with existing experimental data and models to analyse the flow fields of VOTUs at different pressures. With the increase of pressure, the maximum temperature of the VOTU rises rapidly and the minimum temperature decreases smoothly. Meanwhile, when the VOTU works under high pressure, the wall thickness and sealing degree of the VOTU design should be increased accordingly, while the inner wall of the VOTU should be made of wear-resistant material to avoid the wear of the VOTU caused by the long-term scouring of the high-speed airflow.
