Measurement of Mixture Mass Ratio by Acoustic Emission Method
Result description
The article deals with solid particle flow measurement by acoustic emission method (AE). The particle, that impacts a waveguide, generates impulse AE. AE signal, measured by a piezoelectric wide-band sensor mounted at the end of the waveguide, carries information about parameters of impacting particles (specific mass, velocity, dimensions). The article is a follow-up to formerly performed measurements that were focused on a research of a correlation between input particle parameters and measured frequency spectrum of AE signal. The article expands this problematic by a study of measured frequency spectrum of two-component mixture, which consists of materials with a different mass ratio. On basics obvious theoretical presumption, it is possible to obtain information about mutual mass ratio from measured signal by statistical analysis. Practical experiments were completed to prove these theoretical presumptions. In the first part of performed experiments, two materials with different gra
