Abstract

The water production performance of a 3D arc-shaped still under all-day variable incident angle conditions was studied using a combination of numerical simulation and experimental research methods. A multi-physics model coupling photothermal conversion, heat transfer and mass transport for 3D arc-shaped still was constructed, and the influence of sunlight incidence angle on the water production performance of arc-shaped still with different height to diameter ratios was analyzed. The simulation results show that as the aspect ratio increases, the arc-shaped still can obtain more total irradiation energy under the condition of oblique sunlight incidence, achieving higher energy conversion efficiency throughout the day. A arc-shaped still with a height to diameter ratio of about 0.8 has a water production efficiency of 57.7%, which is about 5% higher than a typical circular structure.

Key words
