The dense fluidic ash-water mixtures are time dependent, their shearing results in the significant decrease of the pressure drop in the laminar region, also laminar/turbulent transition region were reached for lower flow velocity. Presence of bottom ash or chemical agent affects favourably the flow behaviour of dense fluidic ash-water mixtures. The paper is focussed on the experimental study of the effect of concentration, time and intensity of shearing and particle size distribution on the hydraulic gradient vs. the average velocity relationship in the laminar, transitional and turbulent regimes. The re-circulation pipe loop with smooth stainless steel pipes of the inner diameters D = 26.8 and 36 mm was used for measuring the ash-water mixtures flow parameters.
