Velocity field around droplet was discussed during single droplet combustion in DC electric field. Tracer particles were inserted into combustion and electric field and velocities of them were measured using PTV method. Toluene droplets were burned between plate electrodes and DC voltages are applied between them. Experimental results show the velocity of tracer particle is uniform without flame, on the other hand, it is not uniform with flame. This indicates the tracer particles are considered to be charged in this case. This result also indicates that flame deforms the electric field because it contains many ions. This information is important because the deformation will induce ionic wind around droplet.
