The present investigation has been excuted for the following two aims. The first one is to find experimentally pressure, velocity and temperature fields of a vortex tube. This is accomplished with that whose chamber diameter is larger compared to nozzle's one, at a nozzle-inlet pressure of 2atg, throughout a range of cold air extraction ratio from 0 to 1. The temperature and pressure distributions are scaned by six Pitot-tubes along the tube diameters. The main result from this measuring is, 1) The changes in the cold air extraction ratio alter both the distributions in the entire region. And in the cross section here, its distribution shapes 'W'. The 2nd aims are to obtain qualitatively decrease and increase degrees in the temperature, energy separation performances, and to consider possibilities and methods of improving the performances. These are performed with the tube whose cross section area is suitable to nozzle's one, and has two Laval-nozzles to test super-sonic velocity, and in the ranges of inlet pressure of 0.4 - 1.8 atg, and cold air ratio of 0 - 1.0. The pitottube is used only to measure the nozzle's outlet states. The main results are, 1) The increase in nozzle-inlet pressure decreases the cold air temperature, and raise the hot air one. 2) It decreases also the efficiency of cold air separation, but not of hot air's one. 3) The rate of decreasing in performances owing to the inlet-pressure rising, is distinguished when the jet velocity reaches super-sonic range, and it begins to rise when the velocity reaches a Macha number. 4) The nozzle outlet pressure is revealed to be high considerably, when the extraction ratio is not 0.
