Abstract

In the present study, three different fluids with different volumes of nano materials(Al2O3) in the Reynolds range of 3 to 48 thousand were investigated for the purpose of evaluating the effect of using nanofluid in heat exchangers. The converter in the submarine engine come to use of as a motor oil cooler. The results show that the addition of nanoparticles to the base fluid in the lower reynolds results in a higher performance factor in the exchanger. By increasing the volumetric percentage of nanoparticles, the converter's performance factor decreases. Optimum mode and maximum heat exchanger performance, in all volumetric percentages, occurs in Reynolds 20,000 for water and 12,000 for ethylene glycol. In other words, the choice of base fluid with a higher performance factor depends on the Reynolds number range. Also, this study examined sea water as a cooling fluid available to the marine diesel engine.
