Abstract
Oscillatory flow heat transfer is an essential design factor for thermoacoustic refrigerator, especially in a stack of an acoustic refrigerator, regenerator in Stirling refrigerator and related heat exchangers. In the research of the past, the mode of heat transfer of oscillatory flow was mainly classified into laminar and turbulent flow heat transfers. And the space-cycle averaged heat transfer characteristics are well correlated using Nusselt number, Reynolds number, Strouhal number and Prandtl number for the respective heat transfer modes, similarly to forced convective heat transfer. However, the effect of oscillating boundary layer on heat transfer characteristic was not considered. In this study, experimental and analytical investigations were conducted paying attention to the behavior of oscillating boundary layer.
