Compression studies of electrorheological (ER) fluids have been impeded by not knowing the concentration of particles held between the plates. This study presents a technique that calls for using a constant volume setup that solves the problem. This study also includes results on how the concentration of particles and the viscosity of the dispersing oils affect the compression of an ER fluid. The conclusions of this study are that the constant volume squeeze flows of ER fluids are significantly different from what has been predicted with constant volume squeeze flow theories.

Key Words: electrorheology • squeeze flow • compression.
