Pushing Droplet Through a Porous Medium

I use a mechanical model of a soft body to study the dynamics of an individual fluid droplet in a random, non-wettable porous medium. The model of droplet relies on the spring-mass system with pressure. I run hundreds of independent simulations. I average droplets trajectories and calculate the averaged tortuosity of the porous domain. Results show that porous media tortuosity increases with decreasing porosity, similar to single-phase fluid study, but the form of this relationship is different.

Automated summary

By using a mechanical model and conducting numerous simulations, we investigated the dynamics of droplets in random porous media. The results showed that the tortuosity of the porous media increases as porosity decreases, similar to studies on single-phase fluids, but with a different relationship form.
