The shape variation of a rotating liquid droplet is simulated numerically by solving the three-dimensional Navier-Stokes equations using the level set method. The rotation is imposed on the stationary spherical droplet, and the deformation of rotating droplet is observed. The droplet shape varies from a spheroid to a two-lobed shape, and breaks up finally. It is shown for the two-lobed shape that the droplet size increases with decreasing rotation rate. The relationship between the droplet size and the rotation rate is found to be in good agreement with the existing experimental data.
