摘　　要：以3D弧形蒸馏器为研究对象,采用数值模拟和实验相结合的研究方法,构建耦合光热转换、热量传递和质量传输多物理场模型,分析太阳光入射角度对不同高径比的弧形蒸馏器产水性能的影响。模拟结果表明,随着高径比的增大,弧形蒸馏器可在太阳光斜入射工况下获得更多的辐照总能量,实现全天更高的能量转换效率。高径比约为0.8的弧形蒸馏器,在30~150°入射角度范围内的产水效率为57.7%,相对于一般的圆形结构提升约5%。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.
