Hence, methods (e.g. Couette method) used to determine the flow performance of liquids can be adopted to investigate the similar flow properties (e.g. apparent shear resistance) of aerated powders. By this means, the understanding and handling techniques for aerated fine powders can be significantly enhanced. This research aims to investigate the apparent shear resistance of aerated fine powders through a specialised viscometer. Such a viscometer is combined with a fluidisation system and a common rotary viscometer. Three types of fine powders (alumina, cement and flyash) were selected as testing materials. Experimental results indicated that aerated fine powders behave similarly to Herschel–Bulkley non-Newtonian fluids. Subsequently, the apparent shear resistance for three fine powders were modelled by modifying the original Herschel–Bulkley rheology model. Consequently, the apparent shear resistance of a specific aerated powder can be measured and modelled using the bench scale system developed in this study, thus can be utilised to predict the flow performance of fine powders in pneumatic conveyors.]]> Sat 24 Mar 2018 07:16:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42621 Mon 29 Aug 2022 08:53:18 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47559 Mon 23 Jan 2023 13:04:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32536 Fri 15 Jun 2018 14:22:15 AEST ]]>
