Nowadays in industry, under conditions of developed serial production, many types of devices for vortex mixing are manufactured: gases with gases, gases with liquids and liquids with powders.The dispersity of aerosol, gaseous or liquid material fed through the tangential channels of vortex generators determines the type of mixture obtained, ranging from nanocomposite with three-dimensional encapsulation to conventional mixtures.Before leading the mixture out of the forming zone, all its components present a classical vortex tube.At this stage, it is appropriate to ask the question: why such complexity to obtain oil paint?
