| Outline of Final Research Achievements |
In this study, Color Coding Method, a simultaneous two-dimensional measurement system for the surface geometry of liquid film, was developed and applied for the investigation of the evolution process of the contact line of a liquid film falling down on an incline. It is shown that the contact slope parameter scaled by Ca number, previously proposed based on the numerical simulation, is applicable also to the present experimental condition. The formed shape of the contact line was found to be affected by film thickness at the root region of the wavy contact line, which depends on the contact slope and the Ca number.
