Numerical study of a passive solar still with separate condenser

Enhancement of Modified Solar Still Integrated with External Condenser Using Nanofluids: an Experimental Approach

The distilled water productivity of the single basin solar still is very limited. In this context, the design modification of a single basin solar still has been investigated to improve the solar still performance through increasing the productivity of distilled water. The experimental attempts are made to enhance the solar still productivity by using nanofluids and also by integrating the stil...

13 Still separate , still unequal

Four decades after the civil rights revolution began with the Supreme Court’s unanimous 1954 school desegregation decision, Brown v. Board of Education, the Supreme Court reversed itself in the 1990s, authorizing school districts to return to segregated and unequal public schools.... The new policies refl ected the victory of the conservative movement that altered the federal courts and turned ...

Improvement of thermal performance of a solar chimney based on a passive solar heating system with phase-change materials

Passive solar systems such as solar chimneys need solar radiation in order to work. Therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. Phase change materials can save additional thermal energy during the day and release it during the...
