Effect of fin configuration parameters on performance of solar still: A review

Abstract

Drinking water is a necessity not only for humanity but also for the all living organisms available in the earth today. But the availability of the potable water is not in abundant amount; hence clean water is scarce in the world today. Solar desalination system is used to turn the saline water into the freshwater by use of sunrays. Solar still is a device which can be employed for desalination. As the daily productivity of solar distiller is low so, multiple techniques have been used by various researchers to improve its productivity. But work done on the fins to enhance the distillate output is not much. Fin is a low-cost heat transfer enhancement which is used by many researchers in the solar thermal applications. Present review paper shows the use of fins in solar still and how it can be used to enhance the distillate output of solar still. At last, a table is also presented to show the use of fins to increase the distillate output alone and with the use of certain materials.
