Energy Separation Characteristics of Vortex Tubes

Vortex tube is a simple device that can simultaneously produce cold and warm air when compressed air into it. It is widely used industrially mainly for the purpose of cooling things. The aim of the preset study is to have ideas what are the factors that cause vortex tube’s energy separation. In this experiment, the pressure, temperature, and flow rate of the gas flowing in and out of the vortex tube were measured. And the energy balance flowing in and out of the vortex tube is considered. The larger the cold flow fraction, the smaller the enthalpy inflow and outflow, and the greater the internal loss. This is thought to be due to the mechanism for adjusting the cold flow fraction, and increasing the cold flow fraction increases the flow resistance of the vortex tube.
