  • Portable Dental Turbine Unit Work Air Pressure Compressor ...

    An air turbine handpiece is a dental abrasive device that rotates at high speed and uses compressed air as the driving force. It is characterized by its small size, light weight, and painless abrading due to its high-speed rotation, but its torque is small and noise level is high. Thus, to improve the performance of the air turbine handpiece, we conducted a performance test of an actual ...

  • This Compressed Air Turbine Outperforms Wind Turbine

    2007-8-1 · It can be found that the air in the draft tube rotates with the vortex rope. In the area where the pressure is low, the air fraction is high. Figure 12 shows that the pressure difference in Plane-1 section decreases with air admission. The vortex rope is known as the dominating contributor of low-frequency pressure pulsation in the draft tube[3>4].
