When mist flow is injected from a pipe between horizontal parallel disks, a thin liquid film and liquid droplets are left on the lower disk. The behavior of residual liquid on the disk is studied experimentally. The distance between the disks is equal to the inner diameter dn of the pipe joining to the upper disk. The behavior of residual liquid is greatly concerned with the flow near the lower disk. On the lower disk where the ratio of the distance from the center of the disk to dn is 4.3-4.5,the condition of the flow near the lower disk changes. When the velocity of the mist flow in the pipe is high, the residual liquid droplets coalesce at this position. The deformation of the shape of the droplet exposed to air flow depends on the initial shape and the modified Weber Number.
