| Abstract: | This paper deals with the axial heat conduction of an oscillating tube's wall. In condition of constant oscillating frequency and pressure ratio, the changes of isentropic refrigerating efficiency and inferal flow of the tube that are influenced by insulating the axial heat conduction are obtained. The results show that isolating the axial heat conduction can increase the isentropic refrigerating efficiency obviously, delay the forming of shock wave and increase the amplitude of shock wave. |
