| Abstract | ||||
| This paper presents experimental and theoretical investigation of decentralized desalination system based on a humidification-dehumidification (HDH) process. HDH is one of the methods that employed in the decentralized systems in remote areas where there is lack of experienced operators, maintenance and water resources. HDH is suitable for remote areas that require small amount of fresh water. In the current work, a mathematical model is presented to investigate the effect of different operating parameters on the system productivity. A computer program based on MATLAB software is developed to solve the mathematical model and post-process the numerical results. In order to validate the mathematical model and verify the obtained numerical results, an experimental setup of decentralized HDH desalination system is designed and constructed. A series of experimental and numerical runs for different operating parameters are performed. The experimental data are compared with the numerical results and a good agreement in both values and trend is observed. The transient state behaviour of each component of the system and the influence of the different operating parameters on the system productivity are presented theoretically and experimentally. | ||||
