dcterms:description |
Molecules in a fluid close to a solid boundary sometime strike the boundary and transfer momentum to it. Molecules further from the boundary collide with molecules that have struck the boundary, further transferring the change in momentum into the interior of the fluid. This transfer of momentum is molecular viscosity. Molecules, however, travel only micrometers between collisions, and the process is very inefficient for transferring momentum even a few centimeters. Molecular viscosity is important only within a few millimeters of a boundary. The coefficient of molecular viscosity has the same value as the dynamic viscosity. |
