| Abstract: | The stack of the standing-wave thermoacoustic refrigerator was studied,the hydro-and thermodynamical processes near and within a thermoacoustic couple were simulated and analyzed by numerical solution of the compressible Navier-Stokes,continuity,and energy equations for an ideal gas,concentrating on the time-averaged energy flux density in the gas.Energy flow density vector and energy flow density trace cloud were obtained within computational domain.The main effect of energy transfer in the axial direction was the heat conduction term. |
