Environmental Air Quality Control System Based on Gas-Dynamic and Acoustic Principles

The article considers the experimental method and the prototype model of the environmental air analysis system. An overview of the existing devices for solving this problem is made, and the principles of their functioning are listed. The Clement-Desormes method, which became the basis for the development of the proposed prototype, is described in detail. The scheme of the device and the principle of its functioning are described. The values of all the most important physical and structural parameters are given. The article contains a description of the physical phenomena that are involved in the operation of the device, describes the entire mathematical apparatus used. Real experimental data on calculating the air adiabatic index, as well as the result of calculating the percentage of their deviation from the average value, are presented.
