Development of the theory of electrified cylindrical liquid jets continued. The theory was extended to include a quantitative description of the sizes of drops formed from the jet, using a modification of the method used by Rayleigh for the unelectrified case. Test apparatus was constructed to examine the interaction of multiple electrified jets. A systematic examination was made of the jet instabilities, drop-size alteration, and charged-drop interactions, as functions of magnitude of the applied voltage, method of applying the voltage, jet separation, and jet liquid properties. Finally, investigation was initiated of charge accumulation in complex, high-velocity flow systems. Current and voltage measurements were made on test sections of different materials and geometries for a range of liquid conductivity and Reynolds number. Constant cross-section flow passages, as well as test sections containing cross-section or wall-material variations, were studied. The experimental results were correlated or contrasted with the results of theoretical analyses. Author
