The objective of my research is to observe the vaporization behavior and vapor concentration profiles around a fuel droplet undergoing oscillatory motion. Zhu et al [Simulation from an oscillating microdroplet, 2004] and Guan et al. [Mass transfer from an oscillating microsphere, 2002] have already demonstrated the increase of mass transfer rate due to oscillating microdroplet using an octopole double ring electrodynamic balance (EDB) and derived a model to predict this enhancement. To conduct my experiments, I will use a vibrating orifice aerosol generator (VOAG) to create a monodisperse droplet stream and image the droplets using the planar laser-induced fluorescence (PLIF) technique used previously and currently in the lab. The droplets generated by the VOAG will subsequently pass through a charging section and then between two electrodes that form an alternating electric field.  The alternating field will induce oscillatory motion in the charged droplets, in the manner of Lackowski et al. [Unipolar charging of aerosol particles in alternating electric field, 2001].  In order to control the spacing between the droplets, an external amplitude-modulated signal will drive the VOAG, in the manner of Orme et al. [Electrostatic charging and deflection of nonconventional droplet streams formed from capillary stream breakup, 2000]. The resulting images will provide insight into the greatly increased vaporization rate that occurs under such conditions.
