Stud ying the e lectrical c onductivity of magnetite nan ofluid using SW model

Fluids containing suspended nanoparticles called nan ofluids, hav e more usages in agron omy, industry and medicine [۱-۳]. Recent studies show that so me nanofluids may po ssess significantly greater thermal a nd electrical conductivities compared to their b ase fluids. Based on the experimental observations, some different models such as Maxwell’s, Hamilton and Cross er’s and Prasher’s mod els were pro posed to de scribe the thermal beh avior observ ed in nanofluids [۳]. H owever, the results of th e literature survey sho w that there are a few st udies on th e electrical conductivit y (EC) of nanofluids [۱-۳]. Recen tly, in ۲۰۱۲, Shen et al.[۳]proposed a new model to d escribe the EC mechan ism of Zn O nanofluids, we calle d SW model. In the pres ent work, w e measured the EC of magnetite na nofluid after preparation and evalua ted the exp erimental re sults using t he SW mod el.
