| Popis: |
The paper presents an overview of the results of studies of acoustic impedance of orifices with grazing airflow. Empirical models of orifice impedance, which take into account the grazing flow, and the existing methods of measuring the acoustic impedance of orifices and the experimental setup created for this purpose are analyzed. A simpler way of measuring the acoustic characteristics of an orifice with grazing flow is considered. The scheme of the developed measuring installation and its general appearance are given. |
