WebThe compartments were determined by the fluid flow, and the dynamic behavior of the compartments was taken into account. Under normal diurnal load variation, the architecture of the compartments did not change, in contrast to the mass transport between the zones, whereas the sludge removal process made significant changes in the architecture. Weba non-Newtonian Power law model. The relative viscosity (ηr) of the mixture slurry, defined as the suspension viscosity over the viscosity of the suspending medium was found to be increasing exponentially when φ exceeds 0.404. By adopting an experimental approach, the rheological data indicated that φ might reach 0.462. Using the (1− −1 2

WebMar 31, 2015 · The results showed that the low-solids sludge with total solids content (TS) 2–15% was pseudoplastic fluid, and the high-solids sludge with TS 7–15% exhibited thixotropic property. Sludge viscosity increased exponentially with the increasing TS, and decreased in function of power along with the increasing shear rate. WebSep 24, 2002 · If it is not kind of a thickened sludge - let's say up to 1% solid content - I would go with standard water viscosity. Vkin (kinematic viscosity) of water: @ 60^C = 4.78 * 10^-7 m^2/s @ 80^C = 3.66 * 10^-7 m^2/s Usually sludge doesn't get thick if warmed up, not until 100^C (of course!), quite the contrary happens - it gets less viscous! Good luck!
