A common scenario in multiphase flow simulations is the formation of thin fluid films in between colliding fluid masses or between a fluid mass and a surface. These films are very thin (O(100 nm)), and during the direct numerical simulations (DNS) of multiphase flows, it is impractical to resolve their thickness fully due to highly disparate time and length scales. Our approach here is to couple a complex thin film model found analytically to a multiphase solver so that we can capture the formation and evolution of thin films which come into existence in the sub-grid thickness. In this preliminary study, we couple a simple thin film model to a CLSVOF-based multiphase solver to simulate a droplet sliding down an inclined plane. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
