Numerical Modelling in Enhancing the Water Desalination of Active Solar Still System

The scarcity of water is amongst many challenges faced by the modern world.
It is well established that of the 97% of water on earth, only 0.3% is readily available
with minimal treatment. Thus, desalination technologies are adopted as one of the
options to solve the said issue. The most suitable, cheap, easy to use and maintain is
solar still. In a solar still, natural hydrological cycle is mimicked to produce potable
water through evaporation and condensation process. However, most solar stills
produce low yield, making it unsustainable over a long period. Fabrication and
experimentation required to improve this technology is costly, time and energy
consuming, as well as waste of resources. Thus, this research aims to develop a
numerical modelling to enhance the water desalination of active solar still using the
ANSYS Fluent 19.2, a Computational Fluid Dynamic (CFD) analysis software.
