The present paper reports on the influence of system rotation on the heat transfer characteristics of transitional and turbulent zero-pressure gradient boundary layers. A test plate is installed in a wind tunnel, which is rotatable around the axis parallel to the plate leading edge with constant speed of rotation. Local heat transfer coefficient during rotation is determined by employing a thermochromic liquid crystal. Effects of the Coriolis force and the centrifugal buoyancy force have been examined by comparing the heat transfer coefficient with different free-stream velocities, rotational speeds and wall temperatures. It has been revealed that the Coriolis force has significant effect on transitional heat transfer, while its effect on turbulent heat transfer is moderate. The centrifugal buoyancy exhibits additional effects if the thermal loading is high.
