Abstract
We describe a shear device designed to allow the visualization of susp ensions or emulsions under an optical microscope. The optical axis of the microscope is perpendicular to the plane of shear. The detailed ho w profile is determined by numerical simulation with two different asp ect ratios of the flaw cell. We use this shear device to investigate t he structure of dilute suspensions of colloidal magnetic particles sub mitted to a magnetic field and to a flaw. (C) 1998 The Society of Rheo logy.
