abstract

A two-dimensional immiscible droplet deformation phenomena on moving wall in a channel has been simulated using lattice Boltzmann method. The behavior of the droplet is shown with the effects of the contact angle, the velocity of bottom wall, droplet size of the droplet to the displacement fluid are investigated. At the initial state, a droplet with various contact angle between the bottom wall is formatted on the wall in a quiescent fluid. When the bottom moves, the shape of droplet starts to deform. The three patterns of deformation of the droplet corresponding to the contact have been shown in the present study.
