Abstract
This thesis presents the experimentally a solar desalination system based on humidification dehumidification (HDH) method. It’s exploited for the desalination purpose. The solar desalination process is currently operating under the climatological conditions of Suez city, Egypt 29.96°N, 32.54°E. The experimental setup has been designed, constructed and assembled. A set of experimental runs have been carried out throughout this study. The effects of spherical dome at different dome heights of 100mm, 180mm, and 400mm were examined in the present study. The results were carried out at desalination water mass flow rate ranged from 1.51L/min to 3.02L/min. the results also carried out in September to October 2016 of year time. The results showed that; the mass flow rate of hot saline water on fresh water productivity was monitored. • Spherical dome height 400mm produces the highest fresh water productivity at the same condition. • The condensation surface increases the fresh water productivity increase. • The saline mass flow rate increases the fresh water productivity increases. • The spherical dome height of 400mm has more productivities than others spherical dome heights. • The hot saline water of 3.02L/min has the highest values of productivity than others. • The maximum system productivity is (2.68L/m2 ) with the estimated cost (0.12$/L). • The maximum rate of heat transfer of cooling water equals 1.82kW and the maximum rate of heat transfer of saline water = 1.733kW at dome height of 400mm and hot saline water of 3.02L/min. • The maximum efficiency is 58.2% of a dome height of 400mm and hot saline water of 3.02L/min. • The maximum fresh water productivity during a daytime was 8.04kg for dome height of 400mm. • The increase in the spherical dome heights leads to an increase in fresh water ABSTRACT iv productivity. • The increase in the surface area of heat transfer leads to an increase of in the amount of fresh water condensate. • The rate of heat transfer of cooling water increases with the increase of mass flow rate. • The rates of heat transfer increases with increase spherical dome height. • A general correlation of the system efficiency as a function of solar intensity per constant solar intensity, spherical dome height per spherical dome diameter and saline water mass flow rate per maximum saline water mass flow rate were proposed. • The calculated system efficiency (correlated) from the proposed equation was plotted versus experimental data and good agreement was achieved. A comparison between present experimental results and results of previous work was carried out and a satisfactory agreement was achieved.
