Transformation of Solution and Suspension Masses during Their Free Fall in Air

Abstract

The characteristic (longitudinal and transversal) dimensions and velocities of water and aqueous solution and suspension masses deformed in flight have been determined from the results of experimental studies for each transformation stage alongside with the conditions corresponding to interstage transitions. Using NaCl solutions and aqueous suspension with 100–500-μm carbon particles as an example, the effect of typical admixtures and inclusions (for chemical and power generation technologies, as well as in the sphere of safety at relative concentrations of up to 5 wt %) in water masses (initial volumes, 0.1–0.5 L) on the time of their transformation during free fall in air has been estimated. The distribution of the number of liquid fragments detached from the surface of a mass along the trajectory of its flight has been established. A hypothesis about the physics of decomposition processes observed in experiments due to the intensive deformations of water and aqueous solutions and suspensions has been formulated.
