ABSTRACT
The research presents issues related to fluid mechanics, thermodynamics, and statistics. In the first sections, the authors review methods and parameters of fluid measurements. The work mainly emphasizes measurements concerning the parameters of air flows during human breathing. In the following section, the test bench for the analysis is described, and the methodology of data acquisition is described. Finally, the authors present a numerical model of the measurement channel and its calculations compared to measurements from an actual test stand. The data acquirement was performed with LabVIEW, modelling with COMSOL Multiphysics®, and calculations with MATLAB software.
