Abstract: A novel rheometer for measuring shear viscosity in a self-aligned microgap was developed. Drag flow of simple linear motion was created inside two self-aligned parallel plates. A ball-bearing contact between the loading and moving parts was employed to facilitate self-alignment so that gap thickness smaller than those in standard rheometers can be obtained. Analysis based on the lubrication approximation indicated that a self-balancing liquid film can be generated between the two plates during rheological measurement. The new device was successfully used to measure the viscosity of selected fluids. Copyright ? (2014) by the Society of Plastics Engineers.
