An Investigation into the Behavior of Liquid Drops on Heterogeneous Surfaces: A Theoretical and Experimental Approach

We analyzed the results of the sessile drop method to examine experimental data regarding the behavior of liquid droplets on heterogeneous surfaces under the action of a magnetic field, their movement along the surface due to horizontal external forces, and in cases of detachment and dropping of the droplet onto a solid surface, compared to the outcomes of the simulation results obtained using the lattice Boltzmann method within a two-dimensional model. In most cases, there was a satisfactory qualitative agreement observed between the calculated and experimental data. This demonstrates the suitability and effectiveness of the proposed theoretical approach in exploring a broad spectrum of phenomena associated with the contact interaction between liquid and solid heterogeneous phases at both the meso- and macroscopic levels.
