Top 10 facts about the world. Hydrodynamics is the study of liquids in motion. Specifically, it looks at the ways different forces affect the movement of liquids. A series of equations explain how the conservation laws of mass, energy, and momentum apply to liquids, particularly those that are not compressed.
The thickness Î´ of a hydrodynamic boundary layer is defined as the distance from the surface of the body (or from the interface of fluids) at which the velocity in the boundary layer can be considered essentially equal to the velocity in the external stream.ithin a dynamic boundary layer a smooth change in velocity occurs from the velocity of the external stream to zero at the wall as a result of the adhesion of the viscous fluid to the solid surface. Similarly, the temperature and concentration vary smoothly within a boundary layer.
