The objective of this study is to improve the accuracy of numerical model by measuring the temperature and evaporation rate of the liquid film in order to investigate the water transport inside the liquid film during the coating and drying process. Polyvinyl alcohol solution was used as the test solution in the experiments. In previous experiments, the authors used a thin liquid film with a thickness of 0.2 mm, which is close to that of actual technology. However, it was difficult to measure the surface temperature in such a small thickness. Therefore, the authors measured that internal of a 5 mm-thick liquid film, and compared the results with a numerical model.
