Lubricated and Frictional Squeezing Flow
Lubricated and Frictional Squeezing Flow
This Demonstration illustrates the theoretical roles that friction, geometry, and rheological properties of a liquid play in idealized squeezing flow between perfectly parallel plates. It calculates and displays the force for Newtonian and pseudoplastic liquids compressed at different deformation rates in lubricated (frictionless) and frictional modes. It also plots the corresponding force versus height relationship on both linear and logarithmic coordinates.
