Abstract

In this study, drop penetration with high density ratio in LAYERED POROUS MEDIUM is simulated with pseudo- potential lattice Boltzmann model. Due to inherent weakness of this model in simulation of flows with high density ratio, EQUATIONS OF STATE as Redlich-Kwong and Peng-Robinson are employed in the simulation. The influence of temperature in surface tension is also studied. Drop penetration is investigated in a LAYERED POROUS MEDIUM which is made of four different sections. Effects of different factors like porosity, hydrophobicity/ hyrophilicity of surfaces on the penetration rate and pattern is studied. The results illustrate that by decreasing the porosity, the penetration rate is changed. In hydrophilic situation, the penetration pattern is piston-type and in hydrophobic one, the penetration is similar to the finger or finger-type. The penetration pattern in different capillary numbers, viscosity ratios and different regimes are analyzed. The change of penetration pattern by consideration of non-homogenous hydrophilicity is also studied.
