Webb12 sep. 2024 · Slurry pipelines are conventionally designed to operate without a deposit on the pipeline invert – i.e. the minimum operating velocity is greater than the deposition … The deposition velocity was determined by plotting pressure drop as a function of mixture velocity. The deposition velocity was taken to be the velocity at which minimum pressure drop was observed. Table 2 summarizes the properties of solids and slurries used in determining the deposition velocity. Visa mer As the viscosity increases, drag on the particles increases, thus reducing the flow velocity needed to suspend the particles in turbulent flow. To model this boundary, Oroskar and Turian (1980) and Shook et al. (2002) have been … Visa mer The critical deposition boundary for non-Newtonian systems can be obtained by replacing the viscosity term in the Oroskar and Turian (1980) model with a generalized viscosity term.Consider a generalized two … Visa mer At point 3, the gel strength and/or yield stress forces are large enough to suspend the particles in the stagnant core region (Poloski et al. 2009a). … Visa mer This boundary falls in the high rheology region with increasing non-Newtonian behavior (Poloski et al. 2009a; Peysson 2004; Wilson and Horsley 2004).
