Advanced research in instrumentation and control technology
The objective of the project is to develop an ultrasonic viscometer for online monitoring of coal/liquid slurries. The analytical investigation performed during this reporting period is for (1) better understanding of coal-slurry rheological properties, (2) experimental evaluation of proposed ultrasonic techniques for viscosity measurement, and (3) selection of a promising technique for further development. Coal slurries of high particle concentration often exhibit non-Newtonian flow behavior, i.e., the slurry viscosity varies with shear rate. Moreover, the slurry viscosity is also a function of temperature, chemical composition, and particle concentration and size distribution. Therefore, direct online measurement of the coal-slurry viscosity is of importance to diagnostics and control of the slurry flows. Results are briefly discussed.
