Magnetohydrodynamic flow in a permeable channel filled with nanofluid

摘要: In this paper, the problem of laminar Magnetohydrodynamic nanofluid flow in a porous channel is investigated. Optimal Homotopy Asymptotic Method (OHAM) used to solve problem.In order consume CPU time, Galerkin method minimize residual. This investigation compared with numerical (four-order Rung-kutte method) and found be excellent agreement. The base fluid water containing copper as nanoparticle. effective thermal conductivity viscosity are calculated by Maxwell–Garnetts (MG) Brinkman models, respectively. influence three dimensionless numbers: volume fraction, Hartmann number Reynolds examined. results indicate that velocity boundary layer thickness decreases increase nanoparticle fraction it increases increases.
