A NEW HEAT TRANSFER CORRELATION FOR OSCILLATING FLUID FLOW
ABSTRACT
In this study, heat transfer under oscillating flow conditions has been investigated conducting a wide range of experiments using water as the flow medium. Experimental data have been reduced to obtain relevant heat transfer parameters, namely Nusselt number, and compared to those obtained by the previous researchers. The new correlation obtained herein covers a wide range of flow conditions and it takes into account the effect of Prandtl number which is very sensitive to temperature variations, thus it is believed to be a good representation of the physical problem. A total of 27 sets of heat transfer experiments, each representing a different frequency, flow displacement length and heat input, have been conducted. Heat applied is absorbed by concentric-pipe heat exchanger where calculations have been performed.
