Abstract

Humidification-dehumidification (HDH) desalination is ideally suitable for producing water at a community level due to its lower temperature requirement and maintenance. In this paper, a simpler version of the HDH desalination system is studied in which both air and seawater remains in the open cycle and it is heated inside a nanofluid based solar collector. The working fluid in this HDH system is a nanofluid which is having the seawater as the base fluid and having copper (Cu) nanoparticles in a fixed amount such that the mixture of seawater and nanoparticles is able to absorb the large amount of solar energy incident on the collector when nanofluid flows through it. The thermodynamic performance of the overall system is measured in the form of gained output ratio (GOR). The performance of the HDH system is also evaluated as a function of various operating parameters such as nanoparticles amount inside the seawater (ƒv), height (H) and length (L) of the channel and mass flow rate ratio (mw/ma). Along with the GOR, the performance of the system is also quantified in the form of recovery ratio (RR) which is defined as the amount of the desalinated water produced per unit of the feed seawater supplied to the unit.
