Particle speed distribution in an electrostatic particulate suspension (EPS) has been measured by suspending and leaking copper and aluminum particles (63-149 [Mu]m) from a small hole from the top plate of a parallel plate test section. Different speed ranges were determined by capturing particles on epoxy-coated glass slides located at different heights above the test section. Assumed Maxwell speed distribution curves, by two different approaches, were fit to the data. Experimental values of particle speed (average, most probable, rms) were compared to theoretical speed of a single particle. Calculations based on experiment were used to determine the particle number density of the suspension. Three methods were used to verify particle number density: laser beam intensity, count (weight), and particle mass flux. Values between the three methods appear to be in agreement, within experimental error. Experimental values of particle flow rate were compared to theoretical values. Recommendations are suggested for further study.
