“…The slip coefficient value need not be same for a droplet impinging on a same surface with different impact velocities. Often the slip coefficients for impinging droplets were identified on an ad hoc basis by comparing the numerical results with the experiments, see [9], [23]- [25]. The wetting diameter of the droplet has been used as a key parameter to identify the appropriate slip coefficient.…”

Abstract-A mesh-dependent relation for the slip number in the Navier-slip with friction boundary condition for computations of impinging droplets with sharp interface methods is proposed. The relation is obtained as a function of Reynolds number, Weber number and the mesh size. The proposed relation is validated for several test cases by comparing the numerically obtained wetting diameter with the experimental results. Further, the computationally obtained maximum wetting diameter using the proposed slip relation is verified with the theoretical predictions. The relative error between the computationally obtained maximum wetting diameter and the theoretical predictions is less than 10% for impinging droplet on a hydrophilic surface, and the error increases in the case of hydrophobic surface.
