The dynamic shear stress of glass beads has been measured to study the effects of experimental parameters including shearing zone height, water fraction, bead size, and bead size distribution. A method is proposed to obtain the true shear stress from the experimental data. From the results of the experiments, it is concluded that the dynamic shear stress has a maximum or minimum value at some value of each parameter. Void fraction has been measured as a function of applied pressure. Velocity distribution across the shearing zone height has been measured using laser doppler velocimetry. In the next quarter, a study will be done to develop a rheological model by combining the effects of the experimental parameters. In addition, the dynamic shear experiments with coal powder will be started. 3 refs., 7 figs., 6 tabs.
