Abstract
Centrifugal air compressors are used in artificial respiration applications due to their constructive simplicity, robustness and reduced size. This type of compressor is suitable in situations where high output pressures are not required, such as artificial lungs. In this sense, this project tested a physical-mathematical model that allowed us to evaluate, with a great level of detail, the performance of a centrifugal compressor used in artificial respiration applications. The model was validated with experimental data from commercial manufacturers of air compressors. Then, this model was used in the optimization of geometry and operational conditions and artificial breathing applications, where it aimed to reduce energy wear and portable battery-powered applications, for this purpose, eleven losses were implemented following the theoretical model from the Euler equation. After the optimization step, a prototype of the compressor was built on a 3D printer making it possible to obtain a performance curve through the use of pressure, flow, rotation and electric power sensors. The compressor in its optimized form was tested on an artificial lung, using a filling balloon in its simulation, allowing data to be obtained that proved the efficiency of its performance.
