摘要
A cylindrical cavity filled with air is considered. The cavity carries out the vibration movement along its axis. Adiabatic boundary conditions are specified on the lateral surface of the cavity. The boundary conditions at the ends of the cavity are considered in two types-adiabatic and isothermal. The features of acoustic streaming and temperature field are described when the cavity radius increases and the boundary conditions at the cavity ends are changed from adiabatic to isothermal.
