ABSTRACT
Fluids are deformable materials composed of molecules, which show no resistance to shear forces. In principle, even a very small volume of a fluid contains a very large number of molecules associated with the physical behavior of the fluid at different dynamic conditions. As the molecular structures of fluids differ, the behavior of fluids under the action of forces differs considerably. The problem is more complicated when two fluids come close to each other and form an interface. Here, any change in the molecular structure of the interface would affect the flow filed around the interface and vice versa. Therefore, powerful computational techniques are required for comprehensive studies on fluid-liquid interfaces.
