Abstract
An experimental study is performed on thermal fluid transport phenomenon in plate heat exchanger. Emphasis is placed on enhancement of heat transfer performance in plate heat exchanger with the aid of silica-nanofluid as a working fluid. A plate heat exchanger (PHE), manufactured by HISAKA company (RX-O15A-KNHJ-7), is used as the test section. The PHE has 3 stainless steel plates (271.3mm X 136.5mm) with a nominal gap of 2.5 mm between any two plates. Thermal energy of the hot working fluid is transferred to that of the cold one through the titanium plate in the test section. Here, hot and cold working fluids are supplied by the independent loops, i.e., hot and cold fluid loops, respectively. It is found that (i) heat transfer is enhanced due to particle suspension in comparison with the pure working fluid, and (ii) heat transfer performance is substantially intensified with an increase in volume fraction of nanoparticle and Reynolds number.
