Integral treatment for forced convection heat and mass transfer of nanofluids over linear stretching sheet

doi:10.1007/s10483-015-1919-6

摘要/Abstract

摘要： An integral treatment is proposed for the analysis of the forced convection flow of a nanofluid over a stretching sheet. The obtained results agree well with the numerical results. The results of the presented solution provide an analytic solution, which can be conveniently used in engineering applications. Four types of nanoparticles, i.e., alumina (Al₂O₃), silicon dioxide (SiO₂), silver (Ag), and copper (Cu), dispersed in the base fluid of water are examined. The analytical results show that an increase in the volume fraction of nanoparticles increases the thickness of the thermal boundary layer. The reduced Nusselt number is a decreasing function of the volume fraction of nanoparticles.
