Abstract An analytical expression
relating the suspension strength to the individual attenuation coefficients
of the host and included media is derived. This is based on a simple model of
a dilute suspension derived from Wiener's dielectric mixture theory assuming
no interaction between electric fields in the host medium and spherical
inclusions. The suspension layer is presented in the form of two separate
layers: one containing only the dry included
substance and the second containing only the host medium. The layer
thicknesses are proportional to the volume of each of the components in the
suspension. Experimental results for milk and clay-sand slurry are in good
agreement with results predicted by the approximate theory for suspension
strengths between 0.1 and 0.7. This range of validity for the approximate
theory is much wider than that allowed by the definition of a dilute
suspension. |
