The author describes the effect of deformation of a liquid droplet on its displacement due to airstreams. Experiments are conducted using a 60mm×150mm crosssectional and 500-mm-long horizontal air-suction wind tunnel. Uniformly sized liquid droplets produced by the longitudinal vibration of a nozzle are used. The liquid droplets exposed to airstreams are deformed;that is, their size normal to the airstream direction is changed. The projection area of a droplet in relation to airstream direction is expected to greatly influence the displacement of a droplet and the drag;therfore, the longitudinal droplet diameter is measured precisely. The author formulated an equation that quantifies dimensionless droplet displacement with dimensionless exposure time. The equation can be used to predict displacement of droplets with slight deformation. Therefore, the appropriate deformation rate of the droplet applicable to the equation is investigated in detail. The relationship between Weber number and maximum / minimum dimensionless longitudinal droplet diameter is also surveyed.
