This study was concerned with the numerical simulation of a moving drop through a fabric due to a wettability gradient. The wettability gradient was introduced by varying the contact angle along the staggered fibers of a fabric. The unsteady laminar Navier-Stokes equation was solved using a fixed Eulerian unstructured grid. The Volume of Fluid Model (VOF) was used to account for tracking the gas/liquid interface. A water drop was placed on top of the fabric with an initial velocity, and the motion of the drop through the fabric was studied. Several computer simulations under different conditions such as the distance between fibers, contact angle distribution, and drop initial velocity were performed, and the results were compared with each other. In order to verify the accuracy of the computational model, the motion of a drop on a surface due to a wettabily gradient was simulated as a benchmark.
