Abstract :The characteristics of heat transfer and pressure distributions were measured by varying the clearances against the duct wall and the separations of the two thin plates for various arrangements of the thin plates which were oscillated by a flow in a parallel plate duct, with a view to enhancing the heat transfer along the duct. The maximum and mean Nusselt numbers have a Reynolds number dependence of Re^<0.8>, and were 2.3 and l.6 times those in the fully developed turbulent flow, respectively, for air with Reynolds number ranging from 9000 to 37500. A relatively new technique, i.e., full field infrared imaging, was used to obtain the time and spatial temperature profiles on the wall surface. Contours of the isotherm of the infrared images correspond well to the heat transfer characteristics and flow behavior.
