Research on the stability and convective heat transfer characteristics of nanofluids
Taking Cu nanofluid as an example,the combined effect of surfactant and pH on the stability of nanofluids and the effects of volume fraction and temperature on the convec-tive heat transfer properties of nanofluids were investigated.The results of the study showed that the SDBS surfactant was added and remained stable for up to 11 days at weak acidity.Subjected to different volume fractions and temperatures,Brownian and thermophoretic mo-tions exhibited inconsistent effects on convective heat transfer.In the convective heat trans-fer in ducts,the Nussle number increases with the increase of volume fraction and tempera-ture.
