There are some fluids which offer resistance to motion. This resistance of fluid to motion is like internal friction which is similar to friction when solid moves on a surface. This is called ...

The study of free boundary problems in the Navier-Stokes equations addresses the subtle interplay between the dynamics of viscous, incompressible fluids and the evolution of interfaces whose locations ...
