“…The number of bounces was found to increase exponentially with substrate hydrophobicity as expressed by the contact angle. Remer et al [25] investigated the droplet impact on surfaces with different wetting properties and in the icing conditions. They found that for even high humidity and low temperatures, water did not freeze during impingement on ''smooth'' silica, superhydrophobic substrate.…”

“…From industrial point of view, wetting is of importance when it comes to coating of surfaces to obtain desired hydrophilic or hydrophobic properties. For example, icing of vehicles, especially airplanes, can be remedied by using hydrophobic surfaces [1] and the hydrophilic ones can be used for the sake of anti-fogging [2]. Possible area of applications is extremely vast [3,4], hence the necessity of researching and investigating the wetting phenomena.…”

This work is dedicated to improved modelling of wetting phenomena and contact angles by means of meshless Smoothed Particle Hydrodynamics (SPH) method. For this purpose we modify the surface tension model in the neighbourhood of the triple line. For higher accuracy we also alter the general method of computing the interface normals, by applying a specific smoothing to the field of vectors, and not the phase indicator function. The necessity of proper boundary conditions in SPH is concisely discussed with multiphase systems in mind. The implemented model yields accurate results for a set of static cases, even for very low values of the imposed contact angle, both in the absence and presence of gravity. The results of the calculations of droplets moving along the wall show a great potential of the proposed approach in future applications.

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.
