AN OPTICAL METHOD FOR DETERMINING THE MENISCUS CHARACTERISTICS OF LIQUID FILMS FLOWING IN A GROOVE
摘要
In this article, an optical investigation technique is described for visualizing the cross sections of flowing liquid films and determining the principal geometric characteristics of the meniscus (film height, equation of the meniscus, apparent contact angle, etc.). Flow visualizations are achieved by using a laser-induced fluorescence technique. Image processing then permits extraction of the meniscus curve and quantitative information. This technique is found to be useful to study the variations of the meniscus form for different groove geometries and mass flow rates.
