The swirling flow of N_2-He gas mixtures is experimentally studied in relatively lower density especially in focusing our attention onto experimental methods relevant to low density flows. The swirling flow was produced by a vortex tube with six nozzles tangential to the tube wall. The tube length and the stagnation pressure were varied. The measurement of flow variables was carried out just at the tube exit by the method utilizing the electron beam. The velocity components were measured by TOF method using a pulsed electron beam after detection of the location of the plasma sheet flowing down from the electron beam. The species consentrations were measured by the fluorescence method with an improved light detection technique. Moreover, the rotational temperature of N_2 was estimated by the well established method utilizing the relative intensity of rotational lines. The results show that there exists a sort of similarity for the swirling flow of gas mixtures through a tube and the governing parameter is (L/D) Re^<-1/2> where L is the tube length, D the diameter, and Re the Reynolds number referred to the sonic speed at the nozzle throat and the tube diameter. The swirling ratio near the axis and the number density ratio on the axis depend only on the single parameter above defined, so far as the present experimental data are concerned. |
