| Outline of Final Research Achievements |
To study the washing mechanism of laminated plates with solvent vapor, we have experimentally investigated evaporation dynamics of liquid conined between solid plates under reduced pressure. As the test liquid, we use deionized water and several organic compounds. To visualize the fluid motion in the thin gaps, we adopt sand-blasted glass plates. In the case of water, many tiny spots of semi-dry region appear and expand at the initial stage, which is cavitation of dissolved gas. In organic liquid cases, dried region expands with complicated branching patterns. We investigated various control parameters, such as the influence of the chamber pressure, the surface roughness, and the plate deformation, among which the surface roughness is found to be one of the dominant factors.
