Analysis of applicability of flow-acoustic coupling used for pressure measurement

The CADMD conference series started in Warsaw in 1994 and has been organized annually since then in Poland and Ukraine. The XXIX CADMD 2021 conference took place in Krakow. A short history of the conference can be found on its website: http://cadmd.lpnu.ua/. The aim of the conference is to exchange experiences between scientists of Ukraine and Poland and their young and promising colleagues in modern information technology, the development of CAD in mechanics, teaching methods and the implementation of automated systems in the educational process, and establishing closer ties between researchers. The main topics of discussion are as follows: automated design systems; robotics, mechatronics, and automation; process management, identification, modeling, and modeling of processes and systems; energy systems and environmental protection facilities – microelectromechanical systems; 3D scanning, printing, and augmented and virtual reality; engineering education.

Abstract

This paper presents the concept and results of initial simulations of an acoustic system for absolute pressure measurement. Its working principle is based on a coupling between the flow and acoustic fields. The measurement is performed indirectly. The measurement of absolute pressure is based on measuring the velocity and time of arrival of an acoustic wave and the relationship between the pressure and speed of sound in a given medium. The concept was verified numerically using the finite volume method and the OpenFOAM environment. One possible application of the system is to measure the mean pressure on the walls of buildings.
