摘要: This study aims to investigate the mixing characteristics of a transparent sludge simulant in mechanically agitated model digester using flow visualisation technique. Video images patterns were obtained by recording progress an acid-base reaction and analysed determine active inactive volumes as function time. The doughnut-shaped region formed above below impeller low concentration decreases size with time disappears finally. 'cavern' shaped around solutions higher concentrations increases increasing agitation reaches steady state equilibrium size, which is specific power input. These results indicate that volume jointly determined rheology A mathematical correlation proposed estimate terms yield Reynolds number.
