Webbgraded slurry will tend to be more slowly settling. This is due to the hindered settling effect of the fines in the grading, which effectively increase the viscosity of the liquid component of the slurry mixture. The calculation method used here is not applicable to very closely … WebbA slurry is generally more viscous than a base liquid and behaves as a non-Newtonian fluid. Some equations to estimate the heat transfer characteristics have been pro- posed for the slurry, but most require physical properties that are difficult to know. This is why we employed the correlation based on the apparent viscosity in this study.
