Abstract
The neutral stability conditions are found with allowance for the effects associated with the disappearance of the particle free volume on transition to the close-packed state and the characteristics of the disturbances with the maximum growth rate are investigated on the interval of intermediate and high particle concentrations. Results relating to the effect of quasi-viscous stresses and Brownian motion on flow stabilization on this concentration interval are obtained. The stability of a bounded uniform vertical flow of not too small particles is investigated and the well-known scale effect, associated with the phenomenon of increasing instability on transition from laboratory to geometrically similar industrial apparatus, is examined.
