Liquid-phase mixing and power consumption in mechanically agitated solid—liquid contactors

Particle Concentration and Mixing Characteristics of Moderate-to-Dense Solid−Liquid Suspensions

“…For example, Harrop et al 5 conducted experiments with a Lightnin A-315 (axial-flow) impeller, using sand particles, and observed that concentrations up to 10 wt % (4 vol %) have little influence on the mixing times as compared to those for water alone. This finding differs from the results of both Kraume 6 and Raghav Rao and Joshi, 7 who reported a substantial increase in mixing time, in comparison to the corresponding single-phase value, in the presence of a glass bead suspension at solids concentrations below 2%.…”

The Effect of Particle Dispersion due to Mixing Speed on Spent Coffee Ground Composites

“…Dispersing these particles rapidly would be essentially dispel the local accumulations (Roni et al, 2019). This principle signifies that the speed of mixing would inherently affect the dispersion of the solid (Bujalski et al, 1999;Rao and Joshi, 1988). We could achieve faster homogeneity with higher mixing speeds.…”

Novel Correlation for Critical Speed for Solid Suspension in Stirred Tanks Developed Using Machine Learning Models Trained on Literature Data

“…There are 3240 total points in the experimental data for critical speed for solid suspension ( N js ), which were gathered from 35 distinct research articles (from 1978 to 2020). ,,,,− ,− ,− The “Engauge Digitizer” tool was used to extract graphical data. The authors of the papers studied the effects of different variables on N js like the tank diameter, number of baffles, impeller type, D / T ratio, c / T ratio, number of blades, particle diameter, Δρ/ρ L , solid loading, kinematic viscosity, etc.…”
