Detailed space- and time-resolved flow field and heat transfer information was generated in harmonically ex-cited, gravity-driven films falling over an inclined, heated plane. Simultaneous planar laser-induced fluorescence imaging(PLIF), particle tracking velocimetry (PTV) and infrared thermography (IR) was employed in order to recover space- andtime- resolved film-height, two-dimensional (2-D) velocity, and gas-liquid interface temperature data respectively. Localand instantaneous heat-transfer coefficient measurements (HTC) were also generated, using this information and knowl-edge of the wall temperature at the location where optical measurements were conducted. Our results indicate a strongcoupling between the film height, bulk velocity and flow-rate, on one hand, and the HTC on the other, along the thinnerregions of the examined films. In contrast, the HTC is insensitive to film such variations in thicker film-regions.
