PERFORMANCE STUDY OF A PSEUDO SINGLE ROW RADIATOR OPERATED WITH DIFFERENT NANOFLUIDS

The design of the multi row radiator that is commercially used has some limitations. Among them, there is no sufficient contact surface among the tube rows; therefore, the thermal conduction rate across the tube rows and to the fins is hindered [1]. In this paper, a pseudo–single row radiator was designed to rectify the problem in the multi row radiator design. The 3D modeling software Pro/Engineer was used to design and construct this radiator. The designed radiator's performance was analyzed by using different Nanofluids that include Aluminum Oxide (Al2O3), Silicon Dioxide (SiO2), Copper Oxide (CuO) and Ethylene Glycol with three volume fraction values (0.2, 0.3 and 0.4). The pressure drops, inlet velocities, heat transfer coefficients and heat transfer rates were determined by using Computational Fluid Dynamics (CFD) in ANSYS. The results showed that the CuO Nanofluid gives a better performance in comparison with other Nanofluids
