Investigation of dispersed fluid systems during the cavitation treatment of hydrofuels
Abstract
Results of investigation of the dispersed fluid systems theory and its practical application during the cavitation treatment of hydrofuels are given. Outcomes of biofuel dispersion estimation have been compared from the classic point of view and from the point of view of the dispersed fluid systems theory exemplified as fitting of water droplets diameters distribution function on sizes of water and fuel emulsion.
