Abstracts:
In this paper we investigate the behavior of the films that are on solid and liquid substrates. The results of experiments on the destruction of thin films on the surface of the heavier immiscible fluids in a rectangular pan are presented. Under the influence of the surface tension these holes expanded and in the interaction with the walls deform, radically changing its shape. The experiments executed for the evolution of one hole and two holes with the interaction. For the 3D computer simulation was used lattice Boltzmann equation method (Lattice Boltzmann Equation, LBE) with parallelizing on GPU (Graphics Processing Unit). For parallel computing technology has been used programming software CUDA (Compute Unified Device Architecture). A 3D computer simulation of the destruction of liquid films on the surface of solid and liquid substrates due to the thermocapillary effect (Marangoni effect) is carried out. Simulation of the evolution of the holes in the liquid film for twolayer systems of immiscible liquids is performed.
