Abstract / Description of output

The volume ratio in the total solid particle mixture
is an important parameter indicating the characteristics of
partculate mixtures. Therefore, a simple measurement method is
desirable. In this paper, the normalized permittivity of two groups
of particle mixtures are tested using Electrical Capacitance
Tomography (ECT) with the series and parallel models. The
experimental results show that normalized permittivity changes
obtained from the series ECT model have a very strong linear
relationship with the volume ratio of higher permittivity materials
in the mixture. The Maxwell Garnett Formula (MGF) can predict
the normalized permittivity only after the permittivity of each type
of particle is known. The comparison between two methods
suggests that ECT with series model is a better way for monitoring
the volume ratio in the mixtures with two types of solid particles.
