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

Abstract

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.
