Abstract: The characteristics of a rotary-bladed machine operating in an open-loop gas cycle for cold production are considered. Mathematical modeling of physical and technical processes has been carried out within the framework of numerical integration of the unsteady Reynolds-averaged system of Navier–Stokes equations (URANS). For this purpose, the ANSYS Fluent 2021 R2 software package has been used. The obtained results on the integral performance indicators of the rotary-blade machine allow us to count on its effective use.

Keywords: rotary-blade machine, cooler, non-stationary heat exchange, numerical simulation.
