An experimental heat-transfer system as well as a data reduction procedure was established in this study on the basis of the fundamental theory of liquid crystal thermography with heating at the solid surface. The system was tested by using both the steady-state and the transient methods with single-step heating at the surface. Two problems considered in the test were the flow over a flat plat with an unheated starting length and a uniformly heated cylinder in the cross flow.
