| Research Abstract |
This work proposes that water lens consists of only a transparent sheet and water, and that it concentrates the solar light and heat. Both calculation and experiments confirmed that a half-cylindrical lens could accumulate the light. Analytical equation describing the lens shape was given and solved numerically. The refraction and ray tracing were evaluated for the perpendicular and slant irradiations. It is predicted that there exists the optimal tension for an amount of filled water in the sheet, and that the maximum concentration ratio exceeds, for example, 75 if the width of sheet is fixed at 1m. The concentration effects for the slant ray were also estimated to simulate the sunrise and sunset. These results contribute to the system design of flexible lens corresponding to the solar dairy movement.
