Hk. Kytomaa, THEORY OF SOUND-PROPAGATION IN SUSPENSIONS - A GUIDE TO PARTICLE-SIZEAND CONCENTRATION CHARACTERIZATION, Powder technology, 82(1), 1995, pp. 115-121
There has been recent increasing interest in the acoustic properties o
f suspensions for applications such as ultrasonic particle size and co
ncentration instrumentation. This paper aims to summarize what is know
n about the acoustic properties of suspensions of solids in a liquid a
nd aims to identify the methods that enable useful information to be e
xtracted from sound speed and attenuation information such as particle
size, concentration, and the mechanical properties of the constituent
s. The paper identifies regimes of sound propagation and present model
s for these that can be used for size characterization of slurries.
