Abstract: In this article, an attempt has been made to study the combined effect of ultrasonic fogger and permanent magnets on conventional solar still (CSS) performance. The magnet and fogger will increase the surface area (due to surface turbulence and fogging action) of water on one hand and surface tension (due to magnetisation) on the other. For thermal analysis Chilton-Colburn analogy-based Tsilingiris model has been used. It is observed that the distillate output due to the augmentations has improved by 61.8% with a cost reduction of 32.33%. It has also been observed that solar thermal efficiency of still has increased by 46.73% due to the augmentations.
