Abstract. One of the topical directions of development of the agro-industrial complex of Ukraine is the development of the pig-breeding industry of animal husbandry. The crucial role is played by the process of feeding animals. It is important to develop new designs of apparatus for the preparation of liquid feed based on grain mixtures.
The purpose of research is numerical study of the processes of hydrodynamics and heat transfer in the rotary-pulsating apparatus in the treatment of a water-grain mixture for the preparation of liquid feeds.
The mathematical modeling of the processes of hydrodynamics and heat transfer in the channels of the rotary pulsation apparatus for the preparation of liquid feeds is carried out. The numerical simulation of heat and hydrodynamic processes using the ANSYS Fluent software obtained velocity, pressure, and temperature distributions in the rotor-stator channels. The transformation of the kinetic energy of rotation of the rotor into heat energy is found, which leads to an increase in the temperature of the liquid grain mixture.
Key words: rotary pulsation device, channel, rotor, stator, pressure, speed, temperature
