description | I n this study, the thermal performance of Al2 O3 , TiO2 and ZnO nanofluid in horizontal microchannels was investigated experimentally and numerically. Al2 O3 13nm , TiO2 10-25nm and ZnO 18nm nanoparticles in water to prepare nano-powders with 0.5%, 0.7% and 1.0% volumetric concentration.A set of experiments was set up for experimentation. For this purpose, micro-channels of 20 cm in length were used at different surface temperatures 15, 25, 40 ° C from different materials 400, 750, 1000 μm . In addition, nanofluids with different inlet temperatures, volumetric flow rates 20, 35, 50 mL/min and concentration ratios are used using nanofluids. Temperature, flow and pressure measurements are based on heat transfer, heat transfer coefficient, Nusselt number, pressure drop and friction factor. The values required for the calculations are measured separately. The effects of parameters such as microchannel diameter, particle type, flow velocity and volumetric ratio on the friction factor, temperature distribution, pressure drop, Reynolds and Nusselt numbers with Taguchi method will be determined in the flow program and compared with the experimental study. In addition, this study will be a preliminary model for the design and analysis of new generation cooling radiators with nanofluid which are not used in diesel engines conforming to Euro 5/6 emissions norms. |
