Abstract
The experimental study on gasesous laminar free-jet flow was investigated by applying high voltage alternating current (AC) to the nozzle. The jet flows were affedcted significatly by AC electric fields particularly at high voltages for applied frequencies less than 80 Hz, while those were not responded to further increased frequencies. Under certain AC conditions of applied voltgae and frequency, the laminar gaseous fuel stem was broken down at an axial distance and subsequently separtaed into some parts. The velocity fields in jet flows interactiong with applied electric fields were compared with those without having electric field. Interaction of applying electric fields with laminar free jet flow was discussed in detail, and the possible mechanism was also explained.
