摘要: Abstract A novel multi-effect vertical concentric tubular solar brackish water desalination device is introduced in present study. The consists of four closely spaced pipes, which the feed gets preheated by hot brine to guarantee evaporation efficiency. An experimental investigation and analytical analysis were carried out signify effect carrier gas-water vapor mixture on productivity enhancement device. Different gases used performance evaluation: carbon dioxide, helium, nitrogen, oxygen, air argon. yield top/bottom temperature values condensation surface with different tested. In addition, presented an approach predict theory based internal heat mass transfer mechanism. results indicate that, when heating 80 °C gas rate can reach 1.19 kg/h. It increased 30.76% than air. numerical had been calculated a consistent agreement obtained operation temperatures. Dv under according results.
