Optimised design of intrusive electrostatic sensors for the velocity measurement of pneumatically conveyed particles

摘要

This paper reports recent advances in the optimisation of intrusive electrostatic sensors for the continuous velocity measurement of particles in pneumatic conveying pipelines. The effects of electrode dimensions and intrusion depth on sensor signals and correlation based velocity measurement have been investigated. Different cross sectional shapes of the electrodes have been compared. The optimum intrusion depth for a velocity measurement closest to the true mean velocity in a pipeline with a given velocity profile is established.
