摘要：

An alternative formulation of physical model available in the literature for spherical cap shape droplets moving on a wettability gradient surface has been developed in a previous work explicitly including the effect of contact angle hysteresis. The model is used with independent experimental data allowing determination of the contact angle hysteresis field by the inverse method. Analyses highlighted a huge effect of contact angle hysteresis and of its spatial heterogeneities on the motion of the droplet.
