| 总结: | This study of acoustic wave was motivated by the thermoacoustic refrigerator. Normally acoustic wave is used to create a temperature gradient across the stack in a resonant tube. Numerical simulation of adiabatic acoustic waves in a closed two-dimensional rectangular chamber is considered for this case. The waves are generated by a membrane boundary condition on one wall. The Navier-Stoke system is solved here by assuming constant thermophysical properties of the compressible Newtonian fluid and perfect gas. The results for adiabatic and nonadiabatic cases for velocity profile, temperature distribution and pressure distribution are discussed. |
