Comparative Analysis of the Effect of Joule Heating and Slip Velocity on Unsteady Squeezing Nanofluid Flow

In this paper, we studied unsteady MHD nanofluid squeezing flow between two parallel plates considering the effect of Joule heating and thermal radiation. The governing equations in form partial differential (PDEs) are transformed into a system ordinary (ODEs) with help similarity transformation. obtained boundary value problem is solved analytically by optimal auxiliary function method (OAFM) numerically Runge–Kutta order 4 (RKMO4). OAFM results validated compared to RKMO4. effects physical parameters such as stretching parameter S , Prandtl number id="M2"> Pr Eckert Ec, magnetic id="M3"> M volume friction id="M4"> φ electric id="M5"> E 1 porous id="M6"> γ on velocity, temperature, concentration profiles discussed plots.
