Non-equilibrium deformation of a droplet in an oscillatory shear flow was investigated. Two plates which are set parallel to each other are moved as opposite phase oscillation to make the shear flow. The flow behavior was visualized by High Speed Video-camera with laser light sheet. Silicone oil of 10,000 cSt and Glycerin aqueous solution are used as continuous phase and dispersed phase respectively. We measured the deformation parameters such as D and diot flow direction of a droplet and have compared the non-equilibrium deformation response with the equilibrium one to obtain the relationship between the deformation of a droplet and the transient shear flow.
