The results showed that no improvement in overall heat transfer coefficient was observed for the nanofluids containing 0.42% and 0.84% solid volume ratios with reference to the base fluid, while an improvement of about 10% was obtained for the nanofluids containing 1.68% solid volume ratio. It was found that the friction factors for the nanofluids exhibited a slight increase reference to the base fluid. A performance analysis based on constant pumping power was also performed.eninfo:eu-repo/semantics/closedAccessChange-Material SlurriesTransfer EnhancementTransfer CoefficientThermal-ConductivityPhaseFlowSuspensionsViscosityFluidArticle53123399340810.1007/s00231-017-2072-x2-s2.0-85020251955Q2WOS:000415999800001Q3
