Preferred Label : simple shear;
IUPAC definition : An idealized treatment of a fluid between two large parallel plates (to permit ignoring
edge effects) of area A, separated by a distance h. If one plate moves relative to
the other with a constant velocity V, requiring a force F acting in the direction
of movement, and the density, pressure, and viscosity throughout the fluid are constant,
the Newtonian equation can be coupled with the equations of motion and of continuity
to show that the velocity gradient in the fluid is constant ( V h), and that F/A
η.V/h. This idealized case (simple shear) is sometimes used to define shear viscosity.;
