In order to study the drop capturing capabilities of heterogeneous walls, a numerical method is developed by integrating the generalized Navier boundary condition into front tracking method (FTM) to establish the contact angle model. The numerical simulation of the movement of drops on the heterogeneous wall with non-uniform wetting was carried out. The drop slides on the inclined wall from the uniform wetting part to the non-uniform wetting part. The movement of the drop in the non-uniform wetting area is studied by changing the
