Dynamic and stationary charging of heavy metallic and dielectric particles against a conducting wall in the presence of a dc applied electric field

摘要: Dielectric and metallic paricles (both spherical irregular in shape) the range 29−4760 μm diameter are electrically charged while dynamic or stationary contact with either wall of a parallel‐plate capacitor. The charge distribution received tends to remove any particle from wall. Particles larger than 127 studied individually dc electric field strengths 2−15 kV/cm. Smaller particles mainly form clouds. In presence gravity standard atmosphereic air, motion, once initiated, is continuous between parallel plates both charging resulting motion experimentally theoretically considering as capacitors themselves. For copper single formula Q= (πe) a2EK applies 2EK K=1.64 whether not dynamically statically acquired. an oxide film does alter K. followed simila...
