This paper presents an experimental study on the liquid column behavior, resulted from impingement of two opposed inclined laminar jets in the presence of high voltage dc electric field. Electric field was generated through two stainless steel capillary nozzles which emit the opposed jets. Jets with a collision provide a liquid column which after a short distance its continuity disrupts and droplets is being made. The jet column breakup and droplets formation were investigated by observation of surface waves along the column. Results show that increasing of droplets mean diameter and column deviation, was obtained by the electric field strength increment. Depend on the wave type on thecolumn surface; twofold breakup behavior will be appearing when the active method of induced electric field of high voltage superimposed.
