Abstract: Vortex Tubes and related methods of separating an airflow into a hot airflow and a cold airflow employ a secondary airflow inlet. A Vortex Tube includes a secondary airflow inlet that injects a swirling airflow aligned with a central region of the lumen of a circulating tube. The secondary airflow inlet includes a swirl generator that generates the vorticity of the swirling airflow. The injected swirling airflow increase the inner vortex strength thereby increasing the temperature difference between the hot airflow and the cold airflow.
