Experimental assessment of stepped solar still with hybrid NPCM under magnetic field
Limited access to fresh water sources has raised water shortage as a crisis. Therefore, solar desalinations have received special attention today. A stepped solar desalination device which has 28 steps with a height of 30 mm, a width of 110 mm and a length of 840 mm has been designed, built and used in this research. In order to increase the daily production rate, the device has been tested and optimized in 4 different modes: first mode) simple, second mode) with phase change material (PCM), third mode) with Hybrid Nano phase change material (NPCM), fourth mode) with Hybrid NPCM under magnetic field. The phase change material and Hybrid Nano phase change material have been used as a source of thermal energy storage to continue the desalination of water when the sun sets. After conducting the tests, it was found that the fourth mode of the test, i.e. the Hybrid Nano phase change material under the magnetic field, had a 98% increase in the production rate compared to the simple mode.
