The performance of tilted wick solar stills including new absorber configurations have been investigated. Four solar stills are built, the first one is flat wick solar still (FWSS), the second one is corrugated wick solar still (CWSS), the third one is half barrel wick solar still (BWSS) and the fourth one is conventional solar still (CSS). The modification in the absorber configuration increases the evaporation area for CWSS and BWSS. The new absorber designs are used to reduce the water flow rate through wick to improve the evaporation rate. The measurements showed that, the increase in the daily yields when compared with CSS are 75 %, 93 % and 100 % for FWSS, BWSS and CWSS, respectively. The theoretical model shows acceptable agreement with the measured data. For further enhancement in wick solar still performance, BWSS and CWSS have been tested with phase change material (PCM) mixed with CuO nanoparticles. The results obtained that, the daily productivity for CWSS and BWSS is increased to be 134 % and 124 % over CSS, respectively. Also, the efficiency and calculated cost per liter are 35 %–0.028 $, and 54.5 % –0.023 $ for CSS and CWSS with phase change material, respectively.

已经研究了包括新的吸收器构造的倾斜芯吸式太阳能蒸馏器的性能。建造了四个太阳能蒸馏器，第一个是扁平灯芯太阳能蒸馏器（FWSS），第二个是瓦楞芯灯太阳能蒸馏器（CWSS），第三个是半桶式芯太阳能蒸馏器（BWSS），第四个是常规太阳能蒸馏器。 （CSS）。吸收器配置的修改增加了CWSS和BWSS的蒸发面积。新的吸收器设计用于减少通过油芯的水流速率，以提高蒸发速率。测量结果表明，与CSS相比，FWSS，BWSS和CWSS的每日产量分别增加了75％，93％和100％。理论模型显示出与测量数据的可接受的一致性。为了进一步增强灯芯太阳能静止性能，BWSS和CWSS已通过相变材料（PCM）与CuO纳米粒子混合的测试。结果表明，与CSS相比，CWSS和BWSS的每日生产率分别提高了134％和124％。同样，使用相变材料的CSS和CWSS的效率和每升计算成本分别为35％–0.028美元和54.5％–0.023美元。
