TODO - In this study we explore the underlying mechanisms of droplet actuation and mobility manipulation, when backpressure is applied through a porous medium under a sessile pinned droplet. Momentum conservation and continuity equations along with the Cahn-Hilliard phase-field equations in a 2D computational domain are used to shed light on the on the droplet actuation and movement mechanisms. The droplet actuation mechanism entails depinning of the receding contact line and movement, by means of a forward wave propagation reaching on the front of the droplet. Eventually, the droplet is skipping forward.
