Turian, R M

This is the first quarterly progress report on the subject DOE grant since the starting date of September 1, 1984. During the present reporting period we have been occupied with the details of starting up of the project. Activities during this period have included hiring graduate research assistants for the project, providing them with full details of the research and its objectives, design and construction of research equipment, purchase and installation of coal slurry preparation equipment, setting up of newly purchased research instruments, and testing and calibration of instruments and equipment. Our objective is to test and hopefully establish a definitive method for measurement of yield stress as an intrinsic property (as contrasted to a rheological model parameter) which will then be related to the microstructure of the coal suspension. We have also calibrated the new capillary tubes using Newtonian standards, and tested them extensively using stabilized titanium dioxide dispersions and the laterite slurries discussed above. Among major new instruments that are being set up are the mercury porosimeter and the BET adsorption apparatus. We hope to start preliminary tests on concentrated coal suspensions during the coming period.
