Synopsis

Heat transfer characteristics of pulsating turbulent air ?ow in a pipe heated at uniform heat ?ux were experimentally investigated. The experiments were performed over a range of 10000 < Re < 40000 and 6.6<68 Hz. This situation ?nds applications in modern power generation facilities and industrial pro- cesses. With installing the oscillator downstream of the tested tube exit, results showed that Nu is strongly affected by both pulsation frequency and Reynolds number. Its local value either increases or decreases over the steady ?ow value. The variation is more pronounced in the entrance region than that in the downstream fully developed region. It is observed also that the relative mean Nu either increases or decreases, depending on the frequency range. Although the deviations are small, it seems to be obvious at higher values of Reynolds number. The obtained heat transfer results are classi?ed according to turbulent bursting model and looked to be qualitatively consistent with previous investigations.
