Abstract

 In this work, investigation of the main parameters affecting solar still performance under the weather conditions of the Suez-Gulf area is considered. Three solar still units are designed and constructed with different radii to operate under the same weather conditions with different design parameters. With one fullTSS model and two half-TSS models, three experiments were conducted to study how to obtain the maximum productivity during the day. In every efficient solar still design, water temperature, vapor temperature and distillate output, and difference between water temperature and inner glass cover temperatures are very important. The  purpose  of  this  research  is  to  design  a  water  distillation  system  that  can  purify  water  from  nearly  any source, a system that is relatively cheap, portable, and depends only on renewable solar energy. From the results of project calculations a truthful estimate was made to prototype the most effective geometries of the distiller and trough concentration system, one that will maximize evaporation/condensation and recapture waste heat to minimize thermal losses. Future goals for this project include calculation refinement, material research/testing, and fabrication. The test took place in Suez-Bay (latitude of 29° 966’ and longitude of 32° 549’).
