Abstract
The vibration mode of bend pipe and the choking prevention effect in dense-phase pneumatic conveying has been investigated experimentally. The vibration mode has been showed that it has four antinodes for longitudinal direction, and eight for pipe cross section as designed, and the vibration amplitude has increased as increasing the input voltage. Therefore, it is possible to adjust the vibration amplitude easily by changing the input voltage. Then, the frictional force between the packed bed and pipe wall has been increased with increasing particle diameter. However, it has been reduced with ultrasonic vibration in spite of kinds of particles and pipe diameter. This means the possibility of choking can be removed with ultrasonic vibration in bend pipe as well as in horizontal pipe.
