The flow pattern and the pressure loss of the micro cyclone separator (diameter D=10mm~30mm) have been studied experimentally. The results obtained are as followes : i) The relations between the inlet air velocity V and the pressure loss in the various cyclones shaped such as Fig. 1,are showen in Fig. 2. ii) The pressure loss in the cyclone (Fig. 1,type II) varies completly with the change of cyclone length L, and it is shown in Fig. 5. iii) The static pressure distribution at the inside wall of the cyclone (Fig. 2,typeII) is illustrated in Fig. 6. iv) The pattern of collected talc dust on the inside wall of the cyclone is photographed such as Fig. 8. The pressure loss is minimum in the type II cyclone and it increases as the dimension of the cyclone diameter D. In case of type II, the pressure loss has the sharp peaks at the cyclone length of 2.0D, 5.5D, 9.5D. This strange phenomenon will be due to the efflux of spiral-shaped vortex core from the outlet. The distribution of the static pressure and the talc adhesion on the inside wall reveal obviously the details of the flow pattern in a cyclone.
