Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Question

Consider a flat interface between two immiscible fluids as shown. The flow is parallel in
the x – direction, and the other components are zero. The upper fluid has viscosity µ1 and
the lower fluid u,. Write all the boundary conditions on the interface between the two
fluids.
