Heat dissipation from a heated square cylinder in an oscillating channel flow

Experiments have been performed to investigate heat dissipation from a heated square cylinder in a channel by oscillating flow. During the experiments, the input power and oscillating amplitude (A) are fixed. The effects of the Reynolds number based on the mean flow velocity (Re = 350 and 540) and the oscillating frequency (0 Hzpp~ 2fso), the heat transfer from a square cylinder is dramatically enhanced. The heat transfer enhancement is pronounced as the Reynolds number increases
