Industrial tanks devoted to the mixing of solid particles into liquids are often operated at an
impeller speed N less than Njs (defined as the lowest speed allowing the suspension of all …

In the literature on mechanically agitated solid–liquid systems, several methods are
described to estimate the minimum impeller speed Njs at which all particles are suspended …

Suspensions of solid particles into liquids within industrial stirred tanks are frequently carried
out at an impeller speed lower than the minimum required for complete suspension …

Particle suspension in liquids is a unit operation commonly encountered in the process
industry. Although it is usually carried out in baffled stirred tanks, there are some specific …

Three-phase processes in which particle suspension has to be achieved in conjunction with
gas dispersion are traditionally carried out in sparged, baffled stirred tanks. The operation of …

In the study the results of the friction factor in boundary layer and the distribution of heat
transfer coefficient in non-Newtonian liquid agitated by different impellers, have been …

High-speed mixers are frequently used for suspension of solids. The main goal of our study
was to compare standard mixers with the impeller of a new type designed by Asterion Ltd …

A quantitative methodology for particle suspension assessment is presented. A new
parameter, fmov/tot, the ratio of the mean number of moving particles to the total number of …

This paper deals with the effect of impeller shape on off-bottom particle suspension. On the
basis of numerous suspension measurements, correlations are proposed for calculating the …

In this work, suspension of ultrahigh concentration solids in the presence of gas at different
solids concentrations, gas flow rates, and impeller types was studied in a mechanically …
