ABSTRACTDevelopment of a facility for generating monosized stream of droplets is described in the paper. The technique is based on transverse vibration of a hypodermic needle in which liquid fuel is introduced. This leads to production of drops at a regular frequency. The stream is produced using three types of fuel viz. methanol, aviation kerosene and n-hexane. Information on drop diameters, interdrop distance, drop trajectory is obtained experimentally. Experimental parameters governing the production of a good quality stream have been identified. Experimentally obtained trajectory of the stream is compared with results obtained from a theoretical model.
