• 論文の詳細を見る

• Heat transfer in pulsating laminar flow in a pipe is studied theoretically on the assumption that both the fluid properties and the wall temperature are constant. First, the instantaneous pipe friction factor and the maximum amplitude of pressure-gradient which does not cause a reverse flow are studied. The amplitude of the wall shear stress is represented by a simple equation. Second, the difference in transferred heat between the pulsating case and the steady-state case is studied, and the reason why the locations, where the difference vanishes, appear cyclically in X-direction is explained theoretically. The fluctuations of Nusselt number along X are also illustrated.
