Effect of various parameters on performance of vortex tube: A review Snehal Bharat Bhote Department of Mechanical Engineering, Indira College of Engineering and Management, Pune Savitribai Phule Pune University, India Kiran Devade Department of Mechanical Engineering, Indira College of Engineering and Management, Pune Savitribai Phule Pune University, India Abstract Vortex tube is a simple device used for generation of hot and cold gas streams from single compressed gas supply. It is used in many industrial applications such as electronic component cooling, cooling of equipment in CNC machine, cooling of heat seals and cooling of gas samples etc. Vortex tube is suited for such applications because it is simple, compact, reliable, light…show more content…
[8] 〖∆T〗_c= T_i-T_c (2) Coefficient of performance Coefficient of performance (COP) is defined as the ratio of cooling rate to the energy used in cooling. [7] COP= Q_c/w (3) Cold mass fraction Cold mass fraction is very important concept in case of vortex tube as it indicates vortex tube performance and energy separation inside the vortex tube.[7] It is defined as the ratio of cold gas mass flow rate to inlet gas mass flow rate.[8] µ_c=ṁ_c/ṁ_i (4) Cold orifice diameter ratio Cold orifice diameter ratio is defined as the ratio of cold orifice diameter to the vortex tube diameter. [7] β= d/D (5) Studies of different parameters Fig.3 indicates a plot of working fluids vs. temperature gradient at nozzle number 2 for different inlet pressure experimented by Kirmaci et al. [9] For air as a working fluid, maximum temperature difference 40 K was occur at inlet pressure equal to 700 KPa. Same was observed for nitrogen as a working fluid where maximum temperature difference 40 K was occur at 700 KPa.When oxygen was used as a working fluid maximum temperature difference was 45 K at 700 KPa. Similarly for argon maximum temperature difference 52.1 K was occur at 700
