Fabricate and investigate the performance of the flow-through solar evacuated tube using water-based nanofluids

Experiments are undertaken to determine the efficiency of Evacuated Tube Collector (ETC) using water based Titanium Oxide (Ti02) nanofluid at Pekan campus (3˚30’ N, 103˚ 25’ E) Faculty of Mechanical Engineering, University Malaysia Pahang for conversion of solar thermal energy. These projects are ca...
