comparative study of plane poiseuille flow of non-isothermal ‎couple ‎stress fluid of reynold viscosity model using optimal ‎homotopy ‎asymptotic method and new iterative method

In this paper, we have explored the steady poiseuille flow of couple stress fluid between two parallel plates under ‎the influence of nonisothermal effects of reynold viscosity model, using optimal homotopy asymptotic method ‎‎(oham) and new iterative method (nim). we obtained expressions for velocity profile, temperature distribution, ‎average velocity, volume flux and shear stress. the solutions obtained using these methods are in the form of ‎infinite series; therefore, they can be easily computed. comparative results of solutions obtained by both methods ‎are given using different tables and graphs.
