TY - Type of reference TI - LIF measurements resolved in time of temperature and thickness of a liquid film with surface instability flowing down an inclined surface AU - Romain COLLIGNON AU - Ophélie CABALLINA AU - Guillaume CASTANET AU - Fabrice LEMOINE AB - An optical measurement technique has been developped to characterize the heat transfer in a falling liquid film with surface instabilities, which is flowing down an inclined plane. The waves traveling at the free surface are generated harmonically. The novel technique based on Laser Induced Fluorescence enables to provide simultaneously a measurement of the thickness and the temperature of the liquid film. The experimental results reveal the temporal evolution of the average temperature in the thickness of the film, when the film is travelled by waves of controlled frequency.
