Abstract :In this research, micropolar fluid flow of a porous plate due to Linear stretching is analyzed. The basic partial differential equations are reduced to nonlinear ordinary differential equations which are solved using Homotopy Perturbation Method insert ignore into journalissuearticles values(HPM);. Comparison between results of Flex-PDE software and analytical method of the issue illustrates excellent precision in solving the nonlinear differential equation. Furthermore, impact of injection and suction velocity insert ignore into journalissuearticles values(∅);, coupling parameter between velocity field and micro-rotation field insert ignore into journalissuearticles values(ε);, vortex viscosity parameter insert ignore into journalissuearticles values(β); on micro-rotation, and fluid velocity profiles are examined. Conclusions indicate that: by increasing the ε parameter, the f`insert ignore into journalissuearticles values(η); value decreases. Also, the shear stress F``insert ignore into journalissuearticles values(0); values are gradually reduced with increasing β, while the opposite trend is observed in H` insert ignore into journalissuearticles values(0); variations.
