The present invention provides a process to create without mechanical agitation a zone of low shear, low turbulence flow pattern within a continuous phase liquid contained in a vessel by a continuous or periodic injection of an inert, immiscible, low density fluid, preferably gas, into the liquid to form such a flow pattern, recovering the fluid above the free surface of the liquid, and preferably re-injecting it into the liquid. The invention is particularly useful if the continuous liquid contains a dispersed phase which should be distributed within the continuous liquid without excessive particle agglomeration or breakups in order to largely preserve the initial particle size distribution, or if the initial particle size distribution needs to be modified by controlled breakups of the largest particles, particularly during the subsequent batch processing.
