Torque and displacement data at low shear rate range revealed that the obtained lower apparent viscosity in the in-situ method is not the material characteristics, but the slippage effect due to a preferred location of the bubbles close to the bob, causing an inconsistent decrease of torque and increase of displacement at low shear rate range. In linear viscoelastic regime, the elastic and viscous modulus of sludge was reduced by 33% & 25%, respectively, due to gas injection because of induced shear. The amount of induced shear measured through two different tests (creep and time sweep) were the same. The impact of this induced shear on sludge structure was also verified by microscopic images.]]> Sat 24 Mar 2018 07:39:05 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36654 Fri 15 Sep 2023 14:16:20 AEST ]]>
