【 摘 要 】

The particle size of a slurry and the viscosity of a liquid or slurry are both difficult to measure on-line and in real time. The objectives of this research are to develop the following methods for such measurements: (1) ultrasonic diffraction grating spectroscopy (UDGS) to measure the particle size of a slurry, (2) UDGS to measure the velocity of sound in a slurry using reflection from a grating as opposed to ultrasound traveling through a possibly dense slurry, and (3) shear wave reflection techniques to measure the viscosity of a slurry.
