Modeling the phenomenon of a single droplet impacting a horizontal solid surface is carried out using the finite volume - front tracking method. This work aims to study the characteristics of droplets, especially the density field. The interface is tracked using the front-tracking method based on the location of the density jump. The governing equations used in this modeling are the 2D continuity and Navier-stokes equations for the unsteady and incompressible cases. The validation of this research is done by comparing the results obtained using the implicit scheme with the results developed by Tryggvason 2012 using the explicit scheme. This research shows that surface tension plays an important role in the shape of the droplet when moving and impacting the surface. In addition, the grid size is known to have an influence on this modeling. The smaller the grid size (the more the number of grids), the more accurate the density jump obtained and closer to the exact results. This research is expected to provide a deeper understanding of microscopic phenomena, especially the droplet phenomenon.
