ABSTRACT
This chapter describes the outline of the dispersion methods of agglomerated particles in a gaseous state with particular attention to the external forces that can be utilized for the dispersion force of agglomerates. One of the external forces that can be utilized for the dispersion of agglomerated particles is a fluid resistance induced by the acceleration or deceleration of a fluid. The impaction force which is induced by the collision of agglomerates to the other obstacle has been utilized for industrial dispersers, such as, ball mills and fluidized-bed type dispersers. In the derivation of the dispersion forces, the simple flow field and simple particle behavior are assumed. A pressurized primary air jet generated by a nozzle is introduced into the ejector to induce lower pressure than the atmospheric pressure. In the venture, a low pressure is generalized at the throat, which induces a secondary airflow through the inlet tube.
