Using the effects of hydrodynamic cavitation for purposeful dynamical action on the supramolecular structures

Abstract

Evolution of the cavitation cluster and the level of the dynamic cavitation effects in liquid flow within a Venturi nozzle, depending on the design features and the mode of operation of this type cavitator, are considered. The experimental and theoretical investigations have been performed with the view to using the Venturi nozzle as cavitation reactor to efficient influence supramolecular structures in liquid in relation to producing stable liposome dispersions. Structural peculiarities of liposomes, closed biological nanocapsules, as well as bond energy values in these structures have been analyzed. The results of this study prove that using Venturi nozzles in large-scale production of liposome preparations allows increasing production capacity and significant reduction in the mass-related power consumption as compared with traditional acoustic and hydrodynamic methods.
