HEAT TRANSFER IN OSCILLATING FLOW,
Abstract
Velocity oscillations (associated with pressure oscillations) when imposed upon a compressible fluid in a duct produce increases in the heat transfer between the fluid and the duct. Under certain conditions these increases can be substantial. A limited experimental investiga tion of the nature of these increases is treated. The design principles and capabilities of the elaborate experimental apparatus required to accurately survey the hansfer in a duct at resonant conditions are described. Resonant oscillations in a duct were used to achieve sufficient oscillating amplitudes. The flow characteristics and parametric variations were investigated on at least one-half of a standing wave for all frequencies used. The heat transfer was found to be affected by three-dimensional effects as well as the longitudinal variations, and when such conditions existed, the heat transfer could not be predicted by any simple relationship.
