• In order to study the unsteady heat transfer of oscillating wake flows, the heat transfer characteristics of a cylinder in wake flows behind a cylinder located in oscillating flows were investigated experimentally. The amplitudes of surface temperature, hence local heat transfer coefficient of the cylinder in oscillating wake flows are roughly proportional to those of the main flow velocity and inversely proportional to its frequency, although its time mean is hardly affected by the main flow oscillation. The time-mean and fluctuation of heat transfer coefficient take the maximum at the reattachment of the shear layer separated from the first cylinder, hence the relative position of two cylinders plays an important role on unsteady behavior of heat transfer of the cylinder in the wake flows.
