The research subject is a digital twin of the process of filling the tank with gas mixture components. The aim is to justified choose the digital twin model of the tank filling process with a gas mixture. The task of the study consists of the analysis of construction methods and the operation modes of the digital twin as well as selecting the operation settings of the digital twin model, which ensure a rational reproduction of the gas-dynamic non-stationary of the tank filling process with a component of the gas mixture. The following results were obtained. In accordance with the digitalization concept of modern production, the need to build digital twins for individual physical and chemical processes is substantiated in relation to the researched thermal pulse processing technology. The specifics of the operation of the fuel mixture generator using the critical hole method are determined and the corresponding defining equations for the dosing of gas mixture components and the tank filling time are given for constructing a control system using a digital twin of the process. Existing methods of building digital twins similar to the system under study are analyzed. For further use in the structure of a digital twin of a separate tank filling subsystem, a component of the gas mixture, a finite-element model of gas-dynamic unsteady flow was built and a numerical study was conducted using the ANSYS Fluent software. The dependence on the tank filling time of such basic parameters of the process under study as pressure, temperature, and filled mass of the gas mixture was determined. Reasoned feasibility and developed reduced-order model (ROM model ANSYS Fluent) and used in ANSYS Twin Builder to build a digital twin. Developed and analyzed examples of digital twins of the system of filling the tank with a gas mixture using standard elements of the Twin Builder and Modelica libraries.
