Abstract

The gravity-driven flowing film has been widely used in the fields of heat removal. This work studied film thickness characteristics on the inclined plate with the laser-induced fluorescence technique. The periodic fluctuations of the film were observed, the statistical characteristics of the film thickness were obtained and the three-dimensional structure of the film wave was reconstructed. The experiment results showed that the maximum film thickness increases stepwise with increasing Reynolds number, while the average film thickness increases smoothly. An experimental correlation was proposed by considering the surface waves with variable amplitudes. This new correlation is also in accordance well with other experimental data. Meanwhile, a numerical study based on the diffuse-interface method was conducted. The error between the numerical and experimental results is approximately 10% at the angle of 30°. At angles of 30°, 45°, and 60°, the numerical results showed that the film thickness increased sharply as the distance increases but the rate of growth gradually slows down and remains almost constant when the distance increases continuously. The local velocity of the film is negatively related to the distance from the wall.
