Abstract: A vortex tube (VT) is a very simple, yet effective device to generate instantaneous spot cooling effect, using compressed air as input. Present work is experimental analysis of effect of insulation on temperature separation performance of VT. Firstly, reliability of experimental setup and experimentation procedure is established through observation of transitional characteristics & energy balance. Then, interactive effect of inlet pressure (2–5 bar), cold mass fraction (0.1–0.9) and insulation on the performance of VT is investigated. In the second stage, essential parameters such as temperature and pressure values from experimentation were used to develop computational model of VT and results of experimentation were compared with CFD results. More importantly, utilization of flow physics derived from CFD model has been made to put forth the hypothesis about improvement in performance of VT due to insulation.
