Abstract:

This paper presents the experimental results of the investigation performed on Ranque Hilsch Vortex Tube (RHVT) refrigerator with different control valve location on hot tube outlet side and the effect of wall friction on the inner wall of hot tube. Compressed air at a pressure of 40 psi, 50 psi, 60 psi, 75 psi and 85 psi was introduced at the inlet. At a particular inlet pressure, cooling effect was measured with and without wall friction with respect to valve positions at the hot tube outlet. The result indicates that with wall friction the energy separation is less effective as compared to without wall friction but in both the cases at a particular valve position, maximum energy separation is achieved. The results also indicate a decrease in cold side temperature with an increase in inlet air pressure for a particular valve position for both the cases.
