The article provides an overview of the design features of rotor-pulsation devices in which the method of discrete-pulse energy input is implemented – a method of intensification of heat and mass exchange processes, which contributes to the development and implementation of energy-saving technologies in various industries. The idea of DPEI is to accumulate the energy previously distributed in the working volume in a stationary and arbitrary state in local discrete points of the system and then implement it in pulses to achieve the necessary thermophysical effects. Non-traditional methods of intensification of heat and mass exchange processes by means of discrete-pulse energy input into discrete environments formed the basis of new technologies for obtaining emulsions of various types. In many industries and everyday life, emulsions of various types are widely used, which leads to a constant increase in the requirements for their quality, first of all, stability and uniformity. Therefore, there is a high need for the development of highly efficient equipment and the determination of rational technological modes for processing “liquid-liquid” systems. In the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine, equipment was created, the principle of which is to implement the DPEI method, in particular, rotary-pulsation apparatus (RPA). Rotary-pulsation devices (RPA) are highly efficient, small-sized equipment for creating homogeneous mixtures of various liquids with a wide range of applications. With the help of RPA, issues are optimally solved in many technological processes, such as: dispersion, emulsification, mixing and homogenization of various systems, namely powdery, liquid, multicomponent, high and low viscosity media in many industries. The most important indicator of RPA performance is the size of dispersed emulsion particles obtained after processing in RPA from a mechanical mixture of mutually insoluble liquids or components that are difficult to mix.
