Abstract

Nonsimilar equations exist in many fluid flow problems and these equations are difficult to be solved using variation of the physical parameters. The key purpose of this study is to find nonsimilarity solution of nanofluid on an exponentially shrunk sheet in the existence of micropolar nanofluid without considerations of the thermal radiation and viscous dissipation effects. The governing partial differential equations (PDEs) are transformed into nonsimilar equations consisting of both ordinary and PDEs. Numerical results of velocity, microrotation, heat and concentration are presented in graphs. The results reveal that fluid particles' velocity decreases nearby surface and increases afterward. The skin friction, heat and concentration transfer rate are also plotted to perceive the phenomena with different physical situations. It can be deduced that wall shear force f"(0) is improved by developed effects of micropolar fluid parameter K and reduced by increasing values of Hartmann number M.
