Abstract

This experimental study has been performed to investigate heat transfer enhancement factor E from a heated circular cylinder in a channel by pulsating flow. During the experiment, the effect of the Reynolds number (Re. = 696 and 957) on heat transfer enhancement factor E is examined and the pulsating frequency was kept in the range of 0Hz < fp < 60Hz. This  experiment shows the effects of various gap height (S/D= 2.5, 3.5 and 4.5) on the temperature, Enhancement factor E and Nusselt number with respect to pulsating frequency. It is also revealed that as the gap height decreases, the temperature and heat transfer enhancement factor E increases and the values of Nusselt number also decreases. This experiment shows that value of Reynolds number is increased to increase the value of Nusselt number.
