The results of experiments on the behavior of a simple convective heat exchanger which was subjected to a resonant pulsating flow are described. A 3.86-in. ID horizontal, isothermal tube, 10 ft long, through which air was blown at Reynolds numbers from 2000 to 200,000, was used as the heat exchanger. Both the thermal and the hydrodynamic boundary layers started at the same position in the apparatus. Local heat transfer coefficients were obtained experimentally and compared to equations derived, using a superposition technique, for both the laminar and turbulent regimes.
