| Summary: | This paper presents the second phase of model investigations of static pressure radial distribution conducted on 4 levels of bed height. During the phase the diameter of glass bed particles was increased, blast-furnace pellets were introduced as bed and iron powder was used as powder. Experiments were carried out with regard to gas velocity, bed and powder type and size of bed particles. The radial distribution of 3 fractions of powder accumulated in the bed – static powder, dynamic powder and total powder was calculated from experimentally obtained values of radial distribution of static powder. The influence analysis of the change of investigated bed and powder parameters on values of interaction forces between flow phases as well as on phenomena occurring in the system was conducted. |
