Several types of research have been performed to desalinate the water efficiently. Solar energy, as a low-cost, abundant, and clean energy, has a great potential to alleviate water shortages. Solar water desalination has been considered as an efficient method to utilize in the water desalination process. A solar water evaporation and condensation system are implemented to desalinate water. Solar evaporator system has been proposed and used to produce clean water. High solar energy conversion efficiency requires excellent light absorption, thermal conduction, and water supply performance. Several parameters, such as fluid inlet temperature or inlet velocity, were investigated. The results indicate the best performance in the 1 L/min flow rate and 0.6 m of tube length. Computational fluid dynamics using the COMSOL program was used to analyze the process and find the optimum process conditions.
