| Abstract: | A stick is installed on the central axis in a cyclone separator for stabilizing vortex. The precessing vortex core (PVC) of the improved cyclone separator is measured by means of hot wire anemometry and delt with FFT method. The results show that the stick has effects on decreasing the PVC magnitude.The stick with a longer length and a larger diameter has greater effects on reductions of the frequency, amplitude and area of the precessing vortex core in a cyclone separator. |
