Simulation study of Al2O3-H2O nanofluids as radiator coolant using computational fluid dynamics method

Abstract The objective of this study was to investigate the influence nanofluid concentration on heat transfer rate radiator pipes. This used computational fluid dynamics simulation method ANSYS Fluid Flow Fluent software. working in prepared Al 2 O 3 and H mixture. Simulation performed at various nanoparticles ranging from 0 1%. velocity inlet temperature were set 0.4 m/s 130°C, respectively. results showed that outlet influenced by concentration. increased with Among tested concentration, 1% provided better activity which it is capable reduce high become about 80°C, very close recommended conditions.
