Measurement of velocity and concentration profiles of pneumatically conveyed particles in a square-shaped pipe using electrostatic sensor arrays

Cross-sectional measurement of particle velocity and concentration in a pneumatic conveying pipe is desirable for the characterisation flow dynamics determination mass rate. In this study, an inner-inserted electrostatic sensor array consisting nine pairs electrodes implemented to measure cross-sectional profiling particles over whole cross section square-shaped pipe. Experimental tests were conducted on both vertical horizontal sections test rig under dilute conditions with different air velocities rates. Test results show that slope-shaped profile changes arch-shaped one when from one. The pipes. A comparative study mean measured by developed arrays conducted.
