Abstract
Intensive work is underway in Ukraine and abroad to develop a new generation of high-performance equipment for forming, pumping, transporting, separating using different designs of roller working bodies. The basic requirement for the design of such equipment is to provide the possible designs according to the specifications of the customer in a short interval of time with low costs and high reliability. Industrial technologies require the development of computer-aided software systems that will quickly respond to today's demands for machine longevity and quality. Working environments in their composition and nature are very diverse. They can be conditionally divided into gaseous, liquid, solid, containing chemical and surfactants. The article deals with environments with the composition of chemical and surfactants which, when they reach the surface of the moving rolls, cause corrosion destruction and wear or corrosion-mechanical actuation. Since friction is always accompanied by heating under conditions of corrosion-mechanical wear, the duration of setting the temperature in a sensitive environment is of decisive importance for evaluating the quality of thermoregulation, which is of particular interest in terms of comparing the quality of the sensitive roll in the old and new designs. It is established that the temperature of the environment varies not only in time, but also in the height of the working chamber, since the hydrodynamic process is quite complex, and therefore we provide ways to study the nature of this process with due accuracy set the heat transfer coefficient. With the high intensification of heat transfer processes, it was noted that it is impossible to determine the coefficient of heat transfer – too difficult hydrodynamic conditions.
Keywords: surfactants, environment, hydrodynamic process, coefficient of heat transfer, friction forces, rolls
