Modeling of Gas-Dynamic Processes of Wave Low-Temperature Heat Generators Dynamic Gas Distribution

Abstract

With the development of modern technologies, the application of mathematical modeling in studying various physical processes has become a very relevant topic for researchers. The rapid change of physical processes does not allow for studying the process more deeply, which is precisely what prompts the researcher to use modeling and sequential programming of mathematics. Developing the theory of nonlinear oscillations of real systems encountered various difficulties; therefore, experiments of gas-dynamic oscillations on simple models are quite relevant. Analyzing the development of refrigerating technology and mathematical modeling, a promising method of obtaining cold was chosen based on the oscillating process of gases arising in blocked tubes. These processes are included in the operation of cold wave generators. The simplicity of constructions and the quick change of processes in the generator made it possible to use mathematical modeling, allowing you to study the processes of generators perfectly. Low temperatures and mathematical modeling together went through different stages of development, as a result of which they penetrated various spheres of human activity. The operation of generators is quite interesting from the point of view of the cryogenic and refrigerating direction of the development of machine-less gas-dynamic methods of obtaining low temperatures. This device combines simplicity and reliability of the design, unlike other refrigerating machines, as it has simple moving parts in its design or does not have them at all. Wave generators have found their application in energy, the food industry, and others.
