WALL SLIP CORRECTIONS FOR CAPILLARY, COUETTE, AND PARALLEL DISK VISCOMETERS.

Research output: Contribution to journalArticlepeer-review

Abstract

In measurements of fluid viscosity it is necessary to correct for wall slip to determine the true deformation experienced by the bulk of the sample and the true viscosity. The earlier techniques of Mooney for capillaries and Couette geometries are presented. We present a new analysis of the Couette geometry that requires only two measurements rather than the three used by Mooney. We also present a new analysis for flow between rotating parallel disks. The parallel disk geometry has several experimental advantages for measuring fluid viscosities in the presence of wall slip. Examples are given in the appendices of the analysis of experimental data by these techniques.
