Evaluation of titanium alloy as heat absorber for solar-based water treatment system

Due to the current status of water treatment system it is very difficult to produce fresh clean water without electricity. This research evaluated the intervention of titanium as heat absorber in the heat transfer analysis regarding the solar-based desalination system. The experiment was carried out...
