The flat-plate solar collector (FPSC) three-dimensional (3D) model was used to numerically evaluate the energy and economic estimates. A laminar flow with 500 ≤ Re ≤ 1900, an inlet temperature of 293 K, and a solar flux of 1000 W/m2 were assumed the operating conditions. Two mono nanofluids, CuO-DW and Cu-DW, were tested with different shapes (Spherical, Cylindrical, Platelets, and Blades) and different volume fractions. Additionally, hybrid nanocomposites from CuO@Cu/DW with different shapes (Spherical, Cylindrical, Platelets and Blades), different mixing ratios (60% + 40%, 50% + 50% and 40% + 60%) and different volume fractions (1 volume%, 2 volume%, 3 volume% and 4 volume%) were compared with mono nanofluids. At 1 volume% and Re = 1900, CuO-Platelets demonstrated the highest pressure drop (33.312 Pa). CuO-Platelets achieved the higher thermal enhancement with (8.761%) at 1 vol.% and Re = 1900. CuO-Platelets reduced the size of the solar collector by 25.60%. Meanwhile, CuO@Cu-Spherical (40:60) needed a larger collector size with 16.69% at 4 vol.% and Re = 1900. CuO-Platelets with 967.61, CuO – Cylindrical with 976.76, Cu Platelets with 983.84, and Cu-Cylindrical with 992.92 presented the lowest total cost. Meanwhile, the total cost of CuO – Cu – Platelets with 60:40, 50:50, and 40:60 was 994.82, 996.18, and 997.70, respectively.

收集器技术中单一和混合纳米流体的不同混合比和形态的能量和成本管理

平板太阳能集热器 (FPSC) 三维 (3D) 模型用于对能源和经济估算进行数值评估。500 ≤ Re ≤ 1900、入口温度为 293 K、太阳通量为 1000 W/m 2的层流被假定的操作条件。两种单纳米流体 CuO-DW 和 Cu-DW 以不同的形状(球形、圆柱形、片状和叶片状)和不同的体积分数进行了测试。此外,来自 CuO@Cu/DW 的杂化纳米复合材料具有不同的形状(球形、圆柱形、片状和叶片状)、不同的混合比例(60% + 40%、50% + 50% 和 40% + 60%)和不同的体积分数(将 1 体积%、2 体积%、3 体积%和 4 体积%)与单纳米流体进行了比较。在 1 vol% 和 Re = 1900 时,CuO-Platelets 表现出最高的压降 (33.312 Pa)。CuO-Platelets 在 1 vol.% 和 Re = 1900 时实现了更高的热增强 (8.761%)。CuO-Platelets 将太阳能收集器的尺寸减小了 25.60%。同时,CuO@Cu-Spherical (40:60) 需要更大的收集器尺寸,在 4 vol.% 和 Re = 1900 时需要 16.69%。CuO-Platelets 为 967.61,CuO – Cylindrical 为 976.76,Cu Platelets 为 983.84,Cu-Cylindrical 为 992.92 的总成本最低。同时,60:40、50:50和40:60的CuO-Cu-Platelets的总成本分别为994.82、996.18和997.70。
