Performance of Vortex Tube on Various Geometric Parameters

This paper explains approximately the vortex tube performance based on various geometric parameters inclusive of strain, nature of gas, L/D ratio and boundless mass fractions. The cold end temperature drop was examined as the parameter to be discussed. Inlet pressure varied with an increment of 1 bar from 3 to 5 bars along with thatthe cold mass fraction also varied from 20% to 90%. Maximum cold mass fraction was obtained at 60%. Maximum cold mass fraction was obtained at L/D ratio at 17.5 and at pressure 4 bar. While experimenting the various components like air, carbon-di-oxide and nitrogen gases, the maximumcold mass fraction has been obtained for Co2gas at L/D ratio at 17.5.Maximum temperature gradient occurred at 700 KPa inlet pressure in case of air, nitrogen, oxygen and argon etc. Maximum temperature difference was obtained for argonat 52.1ᵒC. Temperature gradient decreases with increase in nozzle number. Maximum temperature differencewas obtained at nozzle number equals to 2. Finally it has been found that the performance of vortex tube varies due to the level of temperature at differentparameters.
