Моделирование акустического резонанса в сферических резонаторах для прецизионного определения термодинамической температуры
Abstract
A procedure of precise modeling of acoustic resonance in spherical resonators filled with inert gas based on calculation of amplitude and phase of forced gas oscillations in spherical cavity was developed. The theoretical calculation of resonance lines was carried out for different gas pressures and temperatures. The influence of acoustic transducers and holes in resonator walls was theoretically analyzed. The calculated frequency dependencies of acoustic signals were compared with the dependencies measured on experimental spherical resonator filled with gaseous helium.
