EXPERIMENTAL INVESTIGATION OF FORCE CONVECTION HEAT TRANSFER IN A CAR RADIATOR FILLED WITH SIO2-WATER NANOFLUID

In this study, effect of adding in SiO2 nanoparticle in base fluid (water) in car radiator is investigated experimentally. Radiators are compact heat exchangers that optimized and evaluated by considering different working conditions. Car\\\''s cooling system, plays an important role in vehicle\\\''s performance, consists of two main parts, known as radiator and fan. Radiators are compact heat exchangers that optimized and evaluated by considering different working conditions. Car\\\''s cooling system, plays an important role in vehicle\\\''s performance, consists of two main parts, known as radiator and fan. Improving thermal efficiency of engine leads to increase the engine\\\''s performance, decline the fuel consumption and decrease the pollution emissions. For this purpose, an experimental setup was designed. Effects of fluid inlet temperature, the flow rate and nano particle volume fraction on heat transfer are considered. Results show that Nusselt number increases with increase of liquid inlet temperature, nano particle volume fraction and Reynolds number.
