%X Laser Doppler Velocimetry (LDV) was used to measure the flow field in the exit tube of a cyclone separator. It was found that the high speed rotating flow, reverse flow region and turbulent fluctuation were contributed to the pressure loss in the exit tube. When a stick existed in the cyclone separator, the flow field in the exit tube changed, the tangential velocity turned smaller, the reverse flow region disappeared, and the turbulent fluctuation became weaker, so the pressure loss of the cyclone separator decreased. These changes were found to be related to the width and shape of the stick cross-section.
