Abstract

Two-dimensional steady boundary layer flow of nanofluids over a moving impermeable semi-infinite hori-zontal plate is studied. The plate moves with constant ve-locity. Similarity transformation is used to transform gov-erning equations to a nonlinear ODE, which is then solved using the semi-analytical homotopy perturbation method (HPM) for various types of nanoparticles: Cu, Al2O3, TiO2, CuO, Ag and SiO2 in water based fluid. The effect of nanoparticle volume fraction and nanoparticle type on flow characteristics is studied and compared with numerical solution. HPM results agree within 2% error with numerical solution. Analyses show that skin friction coefficient increases with nanoparticle volume fraction increase.
