WebCohesive granular materials such as wet sand, snow, and powders can flow like a viscous liquid. However, the elementary mechanisms of momentum transport in such athermal particulate fluids are elusive. As a result, existing models for cohesive granular viscosity remain phenomenological and debated. WebIn this study, the rheological properties of thermophilic biological sludge (TBS) have been investigated evaluating the influence of non-volatile solids (NVS). Calcium carbonate, sand, and sodium bentonite were separately added to the sludge to evaluate the effect of concentration and type of NVS. Results show that TBS consistency coefficient …

WebApr 6, 2008 · Comparing the flow of sand and other fluids drained through a funnel (0.25′′ opening), we measured a granular viscosity of ∼ 10 −1 Pa s that matches mineral oil viscosity at room temperature. WebOct 1, 2024 · Therefore, it can be argued that the granular bulk viscosity is a function of the particle diameters rather than the dispersity of the particles. However, ballotini particles exhibit a lower bulk viscosity when compared to the sand particles which might be due to their lower densities. Download : Download high-res image (874KB)
