摘要:
Several applications of ultrasonic detectors are suggested for monitoring coal water slurries in coal conversion processes. These include mass flow, particle size, and temperature. Modeling of transmission losses include viscous and thermal transport processes as well as multiscattering effects. Simple monitoring of sound attenuation versus frequency yields a unique dependence from which the value of characteristic parameters may be deduced, all from a single transmitter–receiver pair.
