Serizawa ABSTRACT Oscillating-flow heat transfer is an essential factor for the design of stacks, heat exchangers, and regenerators of acoustic refrigerators. Aiming to have a design basis for such components, experimental and analytical investigations have been conducted into the heat transfer characteristics in an incompressible oscillating flow in a tube. The modes of heat transfer are classified into laminar and turbulent flow heat transfers. The boundary between these modes is closely related to the laminar-to-turbulent transition of flow. The space-cycle averaged heat transfer coefficients are well correlated with Nusselt, Reynolds, Prandtl, and Strouhal numbers.
