Consideration of Thermodynamic Processes Formation of Compressed-Air Foam in Design Compressed Air Foam Systems

Abstract

The main problem with creating compressed air systems is to properly regulate the flow of water and the flow of air that is fed into the mixing chamber so as to continuously provide a foam that must have adequate fire-fighting properties and remain stable over time. The process of obtaining compression foam is a thermodynamic process, which depending on the specified technological factors can be both isothermal and adiabatic. The nature of the process determines both the geometric and physical properties of the foam, and its possible fluctuations can lead to changes in the physical characteristics of the foam. The work provides recommendations for determining the type of thermodynamic process, which makes it possible to improve the accuracy when creating mathematical models of mobile plants for the production of CAF.
