    Diagnostyka przepływu materiału sypkiego podczas grawitacyjnego opróżniania silosu smukłego
    (Wydawnictwa AGH, 2008) Grudzień, Krzysztof; Niedostatkiewicz, Maciej; Chaniecki, Zbigniew
    The paper presents the results of the measurements of the solid concentration changes during gravitational emptying the cylindrical silo. The measurements were taken by applied the non-invasive diagnostic method - Electrical Capacitance Tomography (ECT). The experiments conducted for different initially density of granular material with smooth and rough silo walls. Increasing the wall roughness is a one of the most effective way to reduce the dynamics effects, arousing as the result of the resonance between the trembling of granular material and the silo construction. In order to conduct the detailed analysis of shear zone in the wall profile was applied ECT methodology to visualize the changes of concentration distribution in time and tomography image processing to calculate the characteristic parameters of shear zone.
