▎ 摘　　要

In this paper, unsteady squeezing flow between two moving parallel plates (which is filled with nanofluid) is investigated. The RVIM is used to obtain the solution of the governing equation. The effects of the solid volume fraction and Eckert number on Nusselt number are studied. The results show heat transfer enhancement. Velocity profiles for various moving number have been also obtained. The effect of different types of nanoparticles (Graphene Oxide, Aliminium Oxide, Titanium Oxide, Silver) on the Nusselt number has been studied. The results shows the nanoparticle type is an important factor in the cooling and heating processes. The comparison of obtained results with numerical solutions assures us about the validity and accuracy of the current study.
